Timer - Single Shot
THC / THS Series
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 20A steady, 200A 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 - 600 seconds
in 4 ranges. The THC Series is used for coin
vending applications where fast initiate response
is required .
Operation (Single Shot):
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 .
