IS 60T AC 0-60 sec/min Timed Relay (AC)

The IS 60T AC timer is a simple low cost and versatile timer that is suitable for security, fire, door access, CCTV systems and many other applications where a reliable timer is required.

It has been designed for 12 or 24 volt AC operation and has a double pole relay rated at 8 Amps 240 Volts AC complete with LED indication.

Time intervals:

Range 1           0-60 seconds, adjusted by the potentiometer

Range 2           1-60 minutes, selected by plug in link JP2 and adjusted by the potentiometer.

Two modes of operation are provided and are selected by plug in link JP1.

Mode 1

Link pins 1 and 2 on JP1. The relay activates for the timed period. In Mode 1there are 3 options.

1. With JP4 link out, apply a momentary trigger. The relay will activate for the timed period and then de-energise.
2. With JP4 link in, apply a momentary trigger. The relay will activate for the timed period and then de-energise. The timer will lock out until reset pins JP3 are shorted.
3. With JP4 link out, apply a permanent trigger. The relay will activate for the timed period and then de-energise.

If the trigger is still present, after approximately 3 seconds the timer will start again, creating a continuous cycle of operation. The timer will reset after the trigger has been removed.

Mode 2

Link pins 2 and 3 on JP1. The relay activates after the timed period. In Mode 2 there are 3 options.

1. With JP4 out, apply a momentary trigger. The relay activates momentarily after the timed period.
2. With JP4 link in, apply a momentary trigger. The relay will latch on after the timed period until reset pins JP3 are shorted.
3. With JP4 link out, apply a permanent trigger. The relay will activate after the timed period for approximately 3 seconds and then de-energise. If the trigger is still present the timer will start again, creating a continuous cycle of operation. The timer will reset after the trigger has been removed.

Trigger inputs:

The timer will start when an input is applied to the ‘T’ terminal. The input can be a brief pulse or a continuous signal.
