T10 SERIES
Solid-State On-Delay Timer
Description
The T10 Series on-delay timer is a solid-state electronic device
that provides accurate and reliable timing for control circuits up
to 460VAC. The T10 features a user-selectable time delay from
6 seconds to 10 minutes (0.5 to 12 seconds on the T10S400
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 the T10.
The SPDT contact ratings are 480V @ 240VAC on the 115V and
230V models, and 470VA @ 600VAC on the 460V model.
