TRB Series
Time Delay Relay
DescriptionDescription
Description
DescriptionDescription
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.
OperationOperation
Operation
OperationOperation
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.

the time delay. Loss of input voltage resets the time
delay and output.
