Product Features


The D8 tact switch breaks through the traditional mechanical switch and creates a softer electronic tact switch. Add metal shrapnel or silicone gasket inside. The buttons feel soft and have strong resilience. They have a large and small progress button structure. Ultra-thin structure, the entire panel is close to the wall, and the base ultra-thin structure reserves more wiring positions, which greatly reduces the safety problems of button protrusion or panel deformation due to insufficient wiring space and forced installation.





The network intelligent panel reads and modifies the internal registers through 485 communication to achieve remote monitoring and output control. The communication protocol adopts the standard MODBUS RTU communication protocol. Serial port settings: baud rate "9600", parity bit "none", data bit "8", stop bit "1". The two commands are separated by 100ms. If the instruction is not read within 2 seconds, it will be cleared, and if it is read, it will be cleared immediately. Reading time interval: greater than 20ms.
