M31-AXAX4040G 4DI,4DO M31 series distributed IO host supports Modbus TCP protocol and Modbus RTU protocol for acquisition control

[Communication interface]：RJ45, RS485

[Working voltage]： DC 9～36V

[Product weight]：180±5g

[Introduction]：The M31 series distributed IO host supports Modbus TCP protocol and Modbus RTU protocol for acquisition control. The device supports simultaneous access by 5 clients and supports function codes 01/02/03/04/05/06/15/16. The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray.The product adopts an scalable design in structure. There is no need to purchase the whole machine. This saves costs and facilitates customers to access the current on-site environment; the modules are self-contained.
