Application: Serving as an expansion for UR series equipment, providing additional relay outputs
Communication Method: Modbus RTU protocol via RS-485 interface
Control Method: No operating elements; fully configured and controlled through the RS-485 interface
Communication Monitoring: Supports communication timeout detection, with the relay able to switch to a preset state upon timeout
