IDEC SmartRelay functions 4.4.2 Off-delay Short description When an on-delay is set, the output is reset when the configured time has expired. Symbol in IDEC SmartRelay Wiring Input Trg Input R Parameter Output Q Description You start the off-delay time with a negative edge (1 to 0 transition) at input Trg (Trigger) A signal at input R resets the on-delay time and the output. T is the time that expires after which the output is switched off (1 to 0 transition of the output signal). Retentivity: / = No retentivity R = The status is retentive. Q is set with a signal at input Trg. It holds this state until T has expired. Parameter T Please note the parameter T defaults specified in Chapter 4.3.2. The time for parameter T can be based on the actual value of another, already configured function. You can use the process variables of the following functions: • Analog comparator (actual value Ax - Ay, see Chapter 4.4.18) • Analog trigger (actual value Ax, see Chapter 4.4.16) 120 IDEC SmartRelay Manual
