Time Delay Relays
Dedicated - Single Shot
TSS SERIES
Description
TheTSS Series is a totally solid-state timing module. Its 1A
rated, solid-state output provides an excellent method of
time control for exposures, dispensing, or for increasing or
decreasing a switch closure. Time delays from 0.05 to 600
seconds, in 4 ranges, cover 90% of all OEM applications.
Factory calibration of fixed delays is ±5% and the repeat
accuracy is ±±%. TheTSS Series can be surface mounted with
a single screw, or snapped on a 35mm DIN rail using the
P10±3-±0 accessory adaptor.
Operation (Single Shot)
Voltage must be applied before and during timing. Upon
momentary or maintained closure of the initiate switch, 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.
Wiring Diagram
Reset: Reset occurs when the time delay is complete and the
initiate switch opens. Loss of input voltage resets the time delay
and output.
