Description
The TRB Series combines a 10 A isolated electromechanical relay output with analog timing circuitry. False
trigger of the TRB 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 TRB’s industry standard 8 or 11 pin plug-in base wiring.
Operation
Input voltage must be applied before and during timing.
Upon closure of the initiate switch, the output relay
energizes. The time delay begins when the initiate switch
is opened (trailing edge triggered). The output remains
energized during timing. At the end of the time delay, the
output de-energizes. The output will energize if the initiate
switch is closed when input voltage is applied.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time
delay and output.
