Description

The TRB series combines an isolated, 8 A electromechanical

relay output with digital 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 (Delay-on-Break)

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.
