The advantage of the multi-function relays over mono-function is particularly evident in complex automation systems, because it limits the assortment of modules used, which reduces maintenance costs. Just one spare relay can replace any damaged. |

| FUNCTIONS A. PULSE TRIGGERED WITH RISING EDGE The relay, once triggered, is energized and switches into working position. Counting the time starts. The relay is de-energized and drops out once the preset time has elapsed. Disconnection of supply voltage prior to elapsing the time causes the relay to drop out, the actual elapsed time is reset and the next cycle starts from zero. A1. Power triggering. Counting the time starts once the supply voltage has been applied to A1 connecting terminal. B. PULSE TRIGGERED WITH FALLING EDGE Power s to be continuously ON. The pulse of duration equal to the time is triggered once the voltage has been removed from B2 control input. Disconnection of supply voltage prior to elapsing the time causes the relay to drop out immediately. C. RETRIGGERABLE OFF DELAY Power supply has to be continuously ON. The relay is energized and switches into working position once the voltage has been supplied to B2 control input. Relay drops out once the preset time delay (counted from voltage removal from the control input) has elapsed. Re-applying the voltage to the control input prior to elapsing the time delay causes that the relay does not drop out, and time counting starts from zero once the voltage has been removed again from the control input. Disconnection of supply voltage prior to elapsing the preset time delay causes the relay to drop out immediately. D. SYMMETRIC FLASHER Once the supply voltage has been switched on, the relay starts generating pulses of a period equal to double value of preset time delay and of pulse-filling coefficient equal 1/2. D1. Start from no-pulse state (interruption). The work cycle starts from home position. D2. Start from pulse. The work cycle starts from working position. E. ON AND OFF DELAY- PULSE SHIFTING Upon triggering, counting the time starts. Once the preset time delay has elapsed the relay is energized. Once the voltage has been removed from the control input, the relay is de-energized with the delay equal to the present time delay. F. INTERRUPTION TRIGGERED WITH RISING EDGE Upon triggering with rising edge, the relay is de-energized, and is re-energized once the set time has elapsed. G. PULSE WITH POSSIBILITY TO REDUCE TRIGGERED WITH RISING EDGE The relay, once triggered, is energized and switches to working position. Counting the time starts. The relay is de-energized once the preset time delay has elapsed or new rising (leading) edge appeared at the control input. H. LATCHING RELAY Each time the voltage is supplied to the control input, the state of the relay changes to the reverse one. The time is not counted. |
