描述 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.
