JCK60 and JCK70 LED Indicators
NOTE: The LED is not an indicator of the output state of the timing relay.
One Shot Falling
Edge
Multifunction Timer Upon application of input voltage, the time
delay relay is ready to accept trigger signals.
When the trigger switch closes, the relay
remains in its shelf state. When the trigger
switch opens, the relay contacts change state
and a pre-set time delay begins. At the end of
the time delay, the relay contacts return to their
shelf state unless the trigger switch closes and
opens before the time delay elapses.
Continuous cycling of the trigger signal at a rate
faster than the time delay causes the relay to
remain in its changed state.
JCK70
Watchdog
Multifunction Timer
Upon application of input voltage, the time
delay relay is ready to accept trigger signals.
When the trigger switch closes, the relay
contacts change state and the pre-set time
delay begins. At the end of the time delay, the
relay contacts return to their shelf state unless
the trigger switch closes and opens before the
time delay elapses. Continuous cycling of the
trigger signal at a rate faster than the delay time
causes the relay to remain in its changed state.
JCK70
Trigger On Delay
Multifunction Timer
Upon application of input voltage, the time
delay relay is ready to accept trigger signals.
When the trigger switch closes, a pre-set time
delay begins. At the end of the pre-set time
delay, the relay contacts change state and
remain in that position as long as either the
trigger signal is maintained or the input voltage
remains. If the trigger switch opens during the
time delay, the relay contacts return to their
shelf state.
