Customized I/O interface board designed for special control cabinet requirements. It receives switching, pulse and 4-20mA analog signals from sensors and transmitters, and outputs drive signals to field actuators. Onboard signal conditioning and isolation circuits reduce interference between field side and control side, supporting data interaction with main controller through bus protocol.

Certification: CE

Signal conditioning circuit, isolation chip, bus communication unit, terminal block and status LED. Common faults: signal loss, communication disconnection, channel burnout and terminal poor contact.
