The timer relay unit is configurable to provide a variety of operational functions which are determined via DIL switch settings.
The unit can be supplied from a 17 to 30v dc supply and triggered via a switch -ve input or alternatively activated by a 24v signal such as a fire alarm sounder circuit.
The relay has un-fused 8A double pole changeover contacts which can be used to switch loads or isolate circuits.
Available as a boxed unit with isolate key switch or as a PCB only with self adhesive, Nylon mounting pillars. The key switch isolate inputs on the PCB only version can be utilised with a remote key switch if required (not supplied).
||Following a trigger input the relay will activate after the set delay time.
||Following a trigger input the relay will pulse alternately ‘ON’ and ‘OFF’.
||When key is turned to Isolate position the activation of the relay is prevented.
||Delay time before the relay is switched ‘ON’
||Relay is switched immediately and then delay time before the relay is switched ‘OFF’
||Relay can be disabled for a predetermined time, up to 255 hours.
||The buzzer ticks during a time delay running period, changes to a constant tone when the relay is activated and has slow intermittent beeps when the relay is disabled. (Buzzer can be switched off).
||Yellow constant = relau disabled, yellow pulsing = timed disablement, red constant = relay operated, red pulsing = input active, timer running.
|Trigger Signal (a):
||Provide constant supply voltage (17-30vdc) and activate timer via a switch -ve signal (from clean contacts or open collector outputs), necessary for disablement options.
|Trigger Signal (b):
A 24v signal (can be a polarity reversed signal such as a fire alarm sounder circuit). With this option link the ACT IP to 0v.
Note: With this option no power is available to the unit until the circuit is active and so the indicator & buzzer will not function until power is applied.
