Description
Description: High voltage level trigger refers to a forward voltage between signal trigger end(IN) and power cathode, is a trigger way of connecting anode of power with trigger end. When there is forward voltage or the voltage reaches to a certain trigger amount at the trigger end, relay is actuated. Low voltage level trigger refers to the voltage between signal trigger end and power cathode is 0 V, or voltage of trigger end is lower than that of power anode, and relay is actuated. Usually connect power cathode with trigger end. Specifications: Input Voltage Range: DC 5 V to 12 V Input Control Signal Voltage: High and low voltage level can be set (short circuit boards welding on the back plate, the default is low voltage level) Weight: 39 g(approx.) Input Interface: DC+ DC- CH1: 1 channel relay module signal triggering end Package includes: 1 x Relay Module
