Description
The TRS series combines an isolated, 8 A electromechanical,
relay output with digital timing circuitry. False trigger of the
TRS series by a transient is unlikely because of the complete
isolation of the circuit from the line prior to initiation. The
initiate contact is common to one side of the line and may be
utilized to operate other loads. Installation is easy due to the
TRS’s industry standard 8 or 11-pin plug-in base wiring.
Operation (Single Shot)
Input voltage must be applied to the input 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. Applying input
voltage with the initiate switch closed will energize the load
and begin the time delay.
Reset: Reset occurs when the time delay is complete and
the initiate switch is opened. Loss of input voltage resets the
time delay and output.
