Application Scenarios Distributed I/O networking, motion‑device interconnection, factory field‑bus communication, packaging and logistics automation equipment, multi‑axis machine control systems.

Material Composition

• Housing: Industrial‑grade flame‑retardant plastic
• Internal circuit: FR‑4 PCB, CAN controller chip, isolated power transformer, surge‑protection components
• Bus connector: D‑SUB metal shielded interface

Structural Characteristics Compact plug‑in module for System 2003 rack installation. Two D‑SUB CAN bus connectors on front panel, status LED indicators for bus communication and power status. Back‑plane gold‑plated contacts for system bus connection.

Working Principle The module receives and transmits CAN‑protocol data frames via dual isolated transceivers. It converts data between System 2003 internal back‑plane bus and external CAN field bus, and supplies auxiliary power to field‑connected CAN‑bus nodes.

Installation Requirements

• Install into System 2003 standard rack slot
• Use shielded CAN bus cables for field connection
• Terminate CAN bus endpoints with 120 Ω terminal resistors
• Maintain ventilation clearance for heat dissipation
