# How to program Delta’s plc programming time relay

## Delta plc programming time relay programming method

The Delta PLC timer is a time unit of 1ms, 10ms, 100ms. The timing mode is counted. When the current value of the timer = set value, the output coil is turned on. The set value is the decimal K value. The available data register D is used as the set value.

The actual set time of the timer = the time unit * set value.

Programming can be distinguished according to its nature:

1. General timer:

Generally, the timer is used to count once when the END instruction is running. When the TMR instruction is running, if the timing is reached, the output coil is turned on.

The ladder diagram of the programming looks at the following figure:

#### Programming Examples:

When X0=On, the current value of the timer T0 is counted at 100ms, and when the timer current value = set value K100, the output coil T0=On.

When X0=Off or power failure, the current value of timer T0 is cleared to 0, and output coil T0 becomes Off.

2. Integrated timer

The integrated timer counts once when the END instruction is running. When the TMR instruction is running, if the timing arrives, the output coil is turned on.

The ladder diagram of the programming looks at the following figure:

#### Programming Examples:

When X0=On, the current value of the timer T250 is counted at 100ms, and when the current value of the timer = set value K100, the output coil T0=On.

When X0=Off or power failure during timing, the timer T250 pauses and the current value remains unchanged. When X0 is on again, it continues to count, and its current value is accumulated up until the current value of the timer = set value K100. Coil T0 = On.

How to specify the set value: Actual set time of the timer = Time unit * Set value.

1. Constant specification K: The set value directly specifies the decimal constant K value.

2. Indirect designation D: Set value Use data register D for indirect designation.
