Dual MOSFET Time Delay Switch HW-516 PCB Thermal shutdown and current limitHW 516 Dual MOS tube control board replaces the relay module to trigger the cycle timing delay switch. The timer range is between 0. 1 seconds (minimum) ~ 999 minutes (maximum) continuously adjustable. Features Realize fast and frequent high frequency circuit switching, unlimited switching times; There will be no noise during switching on and off, no sparks, no electromagnetic interference; The service life is longer than that of common
