EBYTE M31-AXAX8080G-U-CAN 8DI+8DO Remote I/O Module - Support Standard CANopen Communication Protocol
The M31-U-CAN series distributed I/O master is a slave module supporting the CANopen protocol. It adopts a modular design, supporting multiple I/O types for flexible expansion according to user needs. Built to Level 3 protection standards, it provides complete isolation for I/O input/output and power supply, offering excellent electromagnetic compatibility, outstanding performance, and high reliability, meeting CE certification standards. The product casing is coated with a conformal coating, providing anti-mildew, anti-moisture, and anti-salt spray functions.
