This module is 8 road digital isolated input, 16 road relay isolated output module, through the isolated RS485 interface output. The module uses standard Modbus RTU communication, can be directly adapted to all kinds of host computer configuration software, PLC, DCS and so on. The module power supply, RS485 communication and electrical signals are isolated from each other, which effectively suppresses all kinds of series mode and common mode interference, and also ensures the stable and reliable operation of the module.
1、the use of RS485, MODBUS, RTU standard communication, with the host computer configuration software, PLC, industrial touch screen, networking, with communication status indicator
2、signal control, power supply, RS485 communication, electrical signals are isolated from each other.
3、communication circuit adopts lightning protection, anti-interference design, power polarity protection.
