Product Description
Multi-voltage delay on opera-
te timer with 6 selectable time
ranges from 0.1 s up to 10 h
for standard 11-pin circular
sockets. Can be configured
with one instantaneous out-
put contact, which can be
used in applications where an
output is desired immediately
when power supply is applied.

Mode of Operation
Contact function 1
DPDT delay on operate
The delay period begins when
power supply is applied. At
the end of the set delay, both
relay contacts will operate and
will not release until power
supply is interrupted. If power
supply is interrupted for at
least 200 ms before the relay
operates, the time circuit is
reset to zero and the relay is
ready for a new time period.
Contact function 2
One instantaneous,
one delayed
Relay contact 2 operates
instantaneously when power
supply is applied. After expi-
ration of the set delay, relay
contact 1 operates.
Both contacts remain in ON-
position until power supply is
interrupted. After 200 ms the
time relay is ready for renew-
ed start.
