SHENZHEN FRIENDCOM TECHNOLOGY DEVELOPMENT CO.,LTDġ Product Description. Loss of input voltage resets the time delay and output.Shenzhen Friendcom Technology Development Co., Ltd.Īddress: 6/F,17 Building, Guangqian Industrial Park, Longzhu Road, Xili Town, Nanshan Reset: Reset occurs when the time delay is complete and the initiate switch is opened. ![]() ![]() Applying input voltage with the initiate switch closed will energize the load and begin the time delay. Opening or reclosing the initiate switch during timing has no affect on the time delay. At the end of the delay, the output de-energizes. Upon momentary or maintained closure of the initiate switch (leading edge triggered), the output energizes for a measured interval of time. Input voltage must be applied to the input before and during timing. Installation is easy due to the TRS’s industry standard 8 or 11-pin plug-in base wiring. The initiate contact is common to one side of the line and may be utilized to operate other loads. False trigger of the TRS by a transient is unlikely because of the complete isolation of the circuit from the line prior to initiation. The TRS Series combines an isolated, 10A electromechanical, relay output with analog timing circuitry.
