Product Overview

The GE Fanuc IC693ACC400 serves as a critical passive component for the Series 90-30 PLC ecosystem. This module terminates serial communication lines within multi-drop or redundant CPU architectures. By providing proper electrical impedance matching, it eliminates signal reflections and ensures stable, high-speed data transmission across the I/O bus expansion system.

Technical Specifications

Engineering Advantages

Signal Stabilization
The IC693ACC400 absorbs stray electrical signals at the end of the communication chain, preventing reflections and minimizing the risk of data corruption in complex PLC networks.

Seamless Integration
Engineers can install the module directly into the expansion port of the Series 90-30 rack without requiring software configuration or additional wiring.

Redundancy Support
In dual-CPU architectures, the terminator maintains communication integrity, enabling seamless failover from the primary to the backup controller.

Zero-Maintenance Design
Its passive, solid-state design eliminates the need for calibration, batteries, or periodic maintenance.

FAQs

Does the IC693ACC400 require a specific slot in the 90-30 rack?
It is typically installed in the last expansion port of the final rack to properly terminate the communication bus.

Can I use this module with Series 90-70 or PACSystems RX3i?
No, this module is specifically designed for the Series 90-30 PLC platform and is not compatible with other GE systems.

Does this module arrive in original GE Fanuc packaging?
Yes, it is supplied as 100% brand new in original factory-sealed packaging.

What happens if I omit the terminator in a multi-rack system?
Omitting the terminator can result in signal reflections, leading to intermittent communication errors or “Loss of I/O” faults.
