Button switch module connect with KC868-Hx smart controller by RS232 port, wall switch panel or any buttons can connect with this board for manual control relay switch. It can use in smart home automation control system or other IOT project.
The performance and features of the button switch module are as follows:
1: DC12V power supply input, and provide DC12V power supply output for the use of third-party equipment.
2: External switch circuit provides independent power supply input interface to improve the anti-interference of long-distance transmission.
3: RS232 communication interface, connected with kc868-hx network relay board.
4: It supports the use of 32 independent wireless remote controllers for each relay. The wireless control distance is open and the theoretical value is 1000m. The actual distance depends on the environment.
5: Long distance switch button connection, the distance between the button and PCB board is up to 300 meters.
6: Support DIN-Rail type installation with special rail buckle.
7: It supports up to 32 key switch connection terminals and “ALL-ON” and “ALL-OFF” special interfaces.
