On-Delay Timers
T10 SERIES
Solid-State On-DelayTimer
Description
TheT10 series on-delay timer is a solid-state electronic device
that provides accurate and reliable timing for control circuits up
to 460 V ac. TheT10 features a user-selectable time delay from
6 seconds to 10 minutes (0.5 to 12 seconds on theT10S400
model) and SPDT output contacts. When power is applied to the
T10, it immediately begins its timing cycle. During this time, the
indicator LED alternates between red and green and the output
contacts remain inactive. When the timing cycle is complete,
the indicator LED turns solid green and the output contacts are
activated. The output contacts will remain activated until power
is removed from theT10.
The SPDT contact ratings are 480 V @ 240 V ac on the 115 V and
230 V models, and 470 VA @ 600 V ac on the 460 V model.
