Single Shot (Pulse Former)

THC & THS Series
Power Timing Module

Description

The TH series is a solid state relay and timer combined into one compact, easy-to-use control. When mounted
to a metal surface, the TH Series may be used to directly control lamp or heater loads of up to 20 Amps
steady 200 Amps inrush. Its single shot function can perform dispensing and pulse shaping operations.
The initiate switch can be a momentary or maintained type of switch. Time delays can be selected from

0.1 seconds to 600 seconds in 4 ranges. The THC Series is used for coin vending applications where fast
initiate response is required.

Approvals:

Operation

Input voltage must be applied before and during timing.
Upon momentary or maintained closure of the initiate
switch (leading edge triggered), the output energizes for
a measured interval of time. At the end of the delay, the
output de-energizes. Opening or reclosing the initiate
switch during timing has no affect on the time delay.
The output will energize if the initiate switch is closed
when input voltage is applied.
Reset: Reset occurs when the time delay is complete
and the initiate switch opens. Loss of input voltage
resets the time delay and output.

Connection

is used when external adjustment is ordered.
