Features: Brand new and high quality Voltage: 5V/12V/24V selectable. Function: Relays turn on when a signal is present, and turn off after the signal disappears. Output: Passive output, a set of relays normally open + normally closed output. Maximum should not exceed 10A. Input: Voltage signal, more than 1.5V is an effective signal, and the current needs at least 0.1mA. Application: Combined with travel switches and induction switches to realize: automatic door closing over time, interruption monitoring of production line product, interruption monitoring of water flow and air flow, other purposes, etc. Specifications: Voltage: 5V/12V/24V Power Consumption: <1.0w Output: Passive output, a set of relays normally open + normally closed output. Maximum should not exceed 10A. Lifespan: More than 100000 actions Input: Voltage signal, more than 1.5v is an effective signal, and the current needs at least 0.1mA.
