Product Description
Mono-function, plug-in mini-
ature interval time relays up
to 600 s (10 min) covering 3
individual time ranges. This
economical timer is often
used in applications such as
lubricating pumps, drying ele-
ments, etc. where an opera-
tion is wanted to last for a lon-
ger period of time.

Mode of Operation
The relay operates and the ti-
me period starts when power
supply is applied to the time
relay.
At the end of the set delay,
the relay releases and will not
operate again until power
supply is reapplied.
A recovery period of 250 ms
should be allowed before re-
applying power supply.
If power supply is interrupted
for more than 250 ms before
the time period has expired,
the relay releases and the time
is reset to zero.
