Product Name

A20B-2901-066 FANUC Series 0i/30i/31i CNC System Digital I/O Interface Module (Core Function: Serving as a “signal conversion hub” for FANUC CNC systems, it enables bidirectional transmission of digital signals between the CNC controller and external equipment (e.g., machine tool sensors, actuators, operation panels), supports custom signal mapping, and ensures precise coordination of CNC machining processes.)

2. Product Description

This module is a key interface component of FANUC’s flagship CNC (Computer Numerical Control) systems, specifically designed for the Series 0i, 30i, and 31i—widely used in metal cutting, milling, and turning machines. It addresses the challenge of reliable signal interaction between high-performance CNC controllers and peripheral machine tool components, with core features as follows:

Dual-Way Digital Signal Transmission: Equipped with multiple independent digital input (DI) and digital output (DO) channels, it can receive status signals from limit switches, photoelectric sensors, and emergency stop devices, while sending control commands to solenoid valves, spindle brakes, and indicator lights. This ensures synchronized actions between the CNC system and machine tool (e.g., triggering tool change sequences after receiving “workpiece in place” signals).

Seamless Integration with FANUC CNC: Leverages FANUC’s proprietary high-speed backplane bus (FANUC Fast Bus) to communicate with the CNC controller, achieving data transmission latency ≤ 5ms—critical for high-speed machining scenarios (e.g., 5-axis contouring). It supports direct configuration of channel parameters (e.g., signal polarity, filter time) via FANUC’s MDI/CRT panel or FANUC LADDER-III software, eliminating the need for third-party gateways.

Industrial-Grade Robustness: Adopts a ruggedized design to withstand harsh machining environments. It features 2500V AC optical isolation between channels and 15kV ESD protection, effectively resisting electromagnetic interference from spindle drives, servo motors, and welding equipment. With an IP20 protection rating (module body), it is suitable for installation inside CNC control cabinets, compatible with aerospace, automotive, and precision mold manufacturing industries.

Maintenance-Friendly Design: Supports hot-swapping (following FANUC CNC system shutdown procedures) for quick replacement during equipment maintenance without disrupting production schedules. It also includes built-in self-diagnostic functions to detect channel short circuits, open circuits, and power anomalies, with fault codes displayed on the CNC system’s CRT for rapid troubleshooting.
