[Size]：110*40*100mm
[Product weight]：180±5g
[Introduction]：M31 series distributed IO host supports Modbus TCP protocol and Modbus RTU protocol for acquisition control.The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. The device supports simultaneous access by 5 clients and supports function codes 01/02/03/04/05/06/15/16.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.
