M31-XAXX0800G 8AI M31 distributed IO host Supports Modbus TCP protocol and Modbus RTU protocol for acquisition control

[Interface]: RJ45,RS485

[Working voltage]: DC 9~36V


[Product weight]:180±5g

[Introduction]: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 product adopts an scalable design in structure. During use, if the user finds that the current device has some functions When the needs cannot be met, you can select the corresponding IO expansion modules according to the missing functions and splice them together to achieve the functions. 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. 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.
