S7300 hardware configuration and module power consumption calculation method

With S7300 313C of CPU added IM365 again extended a machine frame. 313C itself since with 24DI16DO and the simulation entered output 5AI/2AO, see Configuration Manual above CPU behind can placed 8 a module, wants to will about, CPU itself integrated of I/O surface to except did? is regardless of is what CPU Hou end are can placed 8 a module, (manual Shang CPU right shall not installation eight a above of module (SM, and FM, and CP). The cumulative power of the module installed on the rack at S7-300 on the backplane bus must not exceed 1.2 a. ) Cumulative power don’t know what refers all 5V power consumption on a rack? don’t know understand,digital input not available 5V power consumption, only digital outputs and analog inputs and outputs can be found to the 5V power consumption values, use the IM365 extended time frame 1 module can only receive signals; the cumulative current load limits
1.2 a, Bay 1 maximum current of 0.8 a, understandable Bay 0 1.2A Bay 1 maximum can only be calculated 0.8A is it?

The best answer
1, rack according to how many modules problem?
CPU rack called a host when the host rack I/O module (up to 8) of control points is not enough, you can add 1-3 extension rack, each extension rack up to 8 I/O modules, 3 rack up to 24 I/O extension modules.
2, the S7-300 on the backplane bus must not exceed 1.2 a question?
Host backplane bus current is provided by the CPU modules in order to enable theCPU to find the module. Expansion rack backplane bus current is by extension Rackinterface module (IM) to offer. Note that the 5V power supply not power supply module, look know, power supply module is not u-bus connector, CPU modules and extend the rack interface module (IM) u have a backplane bus connector.
U-S7-300 backplane bus connector role and delivers 5V power supply, another roleof the bus connector is communications bus.
No need to take into account the cumulative current load for 5VDC, 8 I/O modulesdo not exceed the sum of 1.2 a/0.8 a Max.
In other words, the CPU module and interface module (IM) up to 8 I/O modules can be installed on the right side, the CPU module and the control module (IM) completely has the ability to provide maximum load 5V power supply.
3, or about 1.2 a 0.8 a?
CPU module with extended Rack interface module (IM) to provide 5V power supply1.2 a/0.8 a, respectively.

Causes and prevention methods of electric line fire

Electrical fire caused by line failure is common for many reasons, mainly below for everyone to resolve the main cause of electric lines caught fire and prevention measures.

A main cause of the fire, electrical lines:

(A) short circuit. So-called short circuit is the circuit of communication two wires touch each other, current does not pass through the line of electrical equipment, and form a loop. Due to the resistance of the wire itself is relatively small, if only throughthe wires of the circuit current will increase rapidly, dozens of times, hundreds of times times greater than normal. Such a large current through a thin wire, due to greater resistance, generated more heat, in a very short period of time the wire has reached thousands of degrees Celsius temperature enough to ignite nearby flammablematerial, causing fire. Is caused by short circuit due to transmission lines used for too long, insulation aging, cracking, loss of insulation, two dash lines; or because thewiring, wire “coat” mechanical damage, causing a short circuit.

(B) poor contact. Due to poor wire joints, causing the line to excessive contact resistance heating fires. Every circuit connector or wire is connected between, or wires and switches, insurance or using equipment. If the connector is not good, would impede the flow of electric charge in the wire, and generate a lot of heat. When these hot enough to melt the wires insulation layer, the insulation would burst into flames and ignited nearby combustibles.
(C) circuit overload. Certain material and cross-sectional area of the wire and have some safe carrying capacity. If the current exceeds its safe carrying capacity of the wire, wires will heat up. Than the more heat the more. When the heat wire temperature exceeding 250 ℃, wire and rubber or plastic insulation fire burning. If a wire “jacket” damage, will cause a short circuit, the greater risk of fire. In addition, if a substandard fuse, circuit overload not found in time, risk becomes a reality.
(D) line leakage. Due to poor insulation of the wire insulation or on scaffolds, wiresand conductors or conductors and the Earth between trace current through. Peopleoften say, leak electricity is a serious phenomenon of leakage. Leakage when Miss spark and temperature can also be the ignition source of the fire.
(E) the spark and arc. Electric spark discharge between the extremes results; arc is formed by the huge swarms of EDM, temperatures can reach 3,000 degrees Celsius or more. Overhead wires swing in the wind, or in case of tree branches slapping, or in case of vehicle when hanging, make two lines touch, discharge, spark, ARC will occur.In addition, the leakage current of insulated wires, wire breakage, short circuit, grounding point and loose wire connections will spark, arc. These electric spark, electric arc, if falling on the combustible, inflammable and may cause a fire.
(F) the cable caught fire. Cable is will burning, is because laying cable Shi its protection lead skin by injury; or in run in the cable of insulation body by mechanical damage, caused cable core and cable core Zhijian or cable core and lead skin Zhijian of insulation body was breakdown and produced arc, led cable of insulation material jute cover occurred burning; or for cable long time overload makes cable insulation performance reduced even lost insulation performance, occurred insulation breakdown and makes cable burning; or because three-phase power system will be three core cable as single core cable using, That Vortex, lead, aluminum skin heating or melting, caused by burning.

Second, the measures to prevent electrical wiring caught fire

(A) in accordance with the required lines. Install electrical wiring must be installed instrict accordance with the electrical regulations, specifically laying electrical lines. Electricians must be certified.

(B) select the correct electrical line. According to the work-life needs, possible loadof suitable specification of electrical lines, don’t over ground for cheap or poor quality wire. Selection of wiring to check whether is a qualified product.
(C) the safe use of electrical wiring. Installed electrical wiring, you cannot just pull, loaded, power out GE, increase the amount of electricity load of the entire line. Note about using the maximum load of the circuit, during use must not exceed this limit, or likely to cause an accident.
(D) always check the electrical circuit. Insist on regular checks, every once in a while is to consult a specialized electrician to help check the electrical wiring, insulation damage found and repaired in a timely manner. Wire age is 10-20 years, and found that age must be replaced immediately.
(E) choose safe electrical switches. To use factor high air switch, try not to use the knife switch. Knife switch on the switch will spark, prone to danger. Choose air switchpower protection role. When fuses are used, to choose the right fuse to avoid failure, the current increases, which can shut off the current.

How to detect the leakage of the line?

General Household circuit, leakage power line zero leakage, if the said method, see:

Electrical lines because of the long service life, it will cause the insulation, insulatorsdamaged, damp or worn insulation layer, produced on the line leakage. In total by one meter on the switch, remove the load and connect the load switch.
If ammeter pointer swings, description line leakage. Cut off the line;
If ammeter pointer does not change between the wire and the earth leakage;
If ammeter pointer back to zero, indicating between FireWire and zero leakage;
If the ammeter indicates smaller, but not zero, it indicates that the line with the zeroline, the line of fire and earth leakage. Remove the branch fuse or operation gate, ammeter, indicates the same leakage indicates that bus; the ammeter indicates zero instructions shunt leakage; the ammeter indicates small, but not zero, it indicates that bus and the shunt leakage. Fixed leakage after the tap, then pull off the lineswitch. When snap to a switch, ammeter, indicates zero, indicating that the line leakage if leakage and elsewhere are also small note that line leakage if all the switchesare pulled off, ammeter that indicates no change indicates that the route of the lineleakage.

If a switch, GFCI tripping, such leakage is the line, check as follows:

1. disconnect the switch, close the General gates, closed one by one separation, which, GFCI jump, is that road has a problem

2. disconnect the appliance plug, plug the electrical plug, which cause the plug to trip, is the question of which electric
3. turn off the lights, lights one by one, into which light caused tripping is the lamp(or line) problems
If the closing does not immediately tripped, for a long time, trip, and trip time inconsistent, which is zero leakage, more professional methods, with Megger (if all the electrical disconnect the plug from the socket or tripping problem should be in line)
Method: take the zero line apart, switch off all, megohmmeter individually check each insulation to ground zero lines, after you identify the problem line, then look at the dedicated line is directly what are the electrical wiring (such as lights or air conditioners) to check if none of electrical business, is the line wrong, only for the line.
Leakage can produce strong electro-magnetic induction lines and wires, you can use a magnetic needle on a piece of paper, and put it to the test site, if the needle deflects to explain.
Electroprobe and multimeter to the most simple tools, best family lines with leakageprotection.
