Multifunction time relay CRM-91H, CRM-93H, CRM-9S
Function
On Delay (Power On)
When the input voltage U is applied, timing delay t begins. Relay contacts
R change state after time delay is complete. Contacts R return to their shelf
state when input voltage U is removed. Trigger switch is not used in this
function.
a
Off Delay
When input voltage U is applied, relay contacts R change state immediately
and timing cycle begins. When time delay is complete, contacts return to
shelf state. When input voltage U is removed, contacts will also return to
their shelfstate. Trigger switch is not used in this function.
b
Repeat Cycle (Starting Off )
When input voltage U is applied, time delay t begins. When time delay t
is complete, relay contacts R change state for time delay t. This cycle will
repeat until input voltage U is removed. Trigger switch is not used in this
function.
c
Repeat Cycle (Starting On)
When input voltage U is applied, relay contacts R change state immediately
and time delay t begins. When time delay t is complete, contacts return to
their shelf state for time delay t. This cycle will repeat until input voltage U
is removed. Trigger switch is not used in this function.
d
Off Delay (S Break)
Input voltage U must be applied continuously. When trigger switch S is closed, relay contacts R change state. When trigger switch S is opened, delay
t begins. When delay t is complete, contacts R return to their shelf state.
If trigger switch S is closed before time delay t is complete, then time is
reset. When trigger switch S is opened, the delay begins again, and relay
contacts R remain in their energized state. If input voltage U is removed,
relay contacts R return to their shelf state.
e
Single Shot
Upon application of input voltage U, the relay is ready to accept trigger
signal S. Upon application of the trigger signal S, the relay contacts R transfer and the preset time t begins. During time-out, the trigger signal S is
ignored. The relay resets by applying the trigger switch S when the relay
is not energized.
U
t
t
Single Shot Trailing Edge (Non-Retriggerable)
Upon application of input voltage U, the relay is ready to accept trigger signal
S. Upon application of the trigger signal S, the relay contacts R transfer and the
preset time t begins. At the end of the preset time t, the relay contacts R return to
their normal condition unless the trigger switch S is opened and closed prior to
time out t (before preset time elapses). Continuous cycling of the trigger switch
S at a rate faster than the preset time will cause the relay contacts R to remain
closed. If input voltage U is removed, relay contacts R return to their shelf state.

Latching relay
Input voltage U must be applied continuously. Output changes state with
every trigger switch S closure. If input voltage U is removed, relay contacts
R return to their shelf state.

Pulse generator
Upon application of input voltage U, a single output pulse of 0.5 seconds is
delivered to relay after time delay t. Power must be removed and reapplied
to repeat pulse. Trigger switch is not used in this function.

Notes
1) Output contacts of CRM-93H do not allow switching of different phases or 3-phase voltages (voltage > 250 V).
2) When mounting into steal-plated switchboards, it is necessary to keep a safety distance of min. 3 mm from terminal’s screws 35-36-38 and 25-26-28 towards the shutter of a switchboard.
