M31-AXXXA000G 16DI 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. This saves costs and facilitates customers to access the current on-site environment; the modules are self-contained. With status diagnosis function, it can monitor the communication status of IO modules in real time; it can support a maximum of 16 IO expansion modules.
