The THDS Series combines accurate timing circuitry with high power solid-state switching. It can switch motors, lamps, and heaters directly without a contactor. You can reduce labor, component cost, and increase reliability with these small, easy-to-use THDS Series timers.


Operation (Single Shot)
必须在计时之前和计时期间施加输入电压。 Upon momentary or maintained closure of the initiate switch, 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. The output energizes if the initiate switch is closed when input voltage is applied.
重置: Reset occurs when the time delay is complete and the initiate switch is opened. 丢失输入电压会复位时间延迟和输出。
