Time Delay Relays
Dedicated - Delay-on-Make
TS1 SERIES
Delay-on-Make Timer
Description
The TS1 Series offers proven reliability and performance with
years of use in OEM equipment and commercial applications.
This encapsulated general use timing module is capable of
controlling load currents ranging from 5mA to 1A. May be
connected in series with contactors, relays, valves, solenoids,
small motors, and lamps.
Operation (Delay-on-Make)
Upon application of input voltage, the time delay begins. The
output is de-energized before and during the time delay. At
the end of the time delay, the output energizes and remains
energized until input voltage is removed.
Reset:
Removing input voltage resets the time delay and output.

BENEFITS
Repeat Accuracy + / - 2%
External time delay settings are adjustable from
0.05s - 10m in 8 ranges for added flexibility
Minimum holding current of 5mA ensures proper
operation with the lightest of loads
No moving parts to arc and wear out over time and
encapsulated to protect against shock, vibration,
and humidity
Allows connection in series with contactors,
relays, valves, solenoids, small motors and lamps.
Provides quick and easy installation for new or
existing systems
