The IC693UEX122 is an integrated I/O expansion unit designed for the GE Fanuc Series 90 Micro programmable logic controller (PLC) product line. This module expands the capabilities of base 23-point and 28-point micro controllers by adding 14 localized input/output points to the process architecture. Featuring an embedded processing core and independent power infrastructure, the unit offloads communication tasks from the main CPU, reducing rack bottlenecks and improving signal execution speeds in distributed control environments.

Features

• Provides 14 additional I/O points (8 DC inputs and 6 DC outputs).
• Integrated high-speed I/O counter for precision signal acquisition.
• Supports daisy-chain configuration for up to four expansion units per base PLC.
• Firmware-level password protection to restrict unauthorized logic access.
• Compatible with Logicmaster 90-3/90-20 software and legacy hand-held programmers.

Applications

This expansion module is suitable for discrete manufacturing lines, municipal pumping stations, and automated packaging systems where additional I/O density is required without replacing the primary controller.

Technical Specifications

Installation Guidelines

• Ensure the system is powered down before connecting or disconnecting expansion modules.
• Follow the strict directional wiring topology: the output connector of the upstream unit must interface with the input port of the subsequent unit.
• Warning: Incorrect reverse connection under live power will cause permanent damage to the internal DC input circuitry.
• Ensure adequate ventilation around the unit to maintain operating temperatures within the 0 to 60 deg C range.
• Use shielded cabling for I/O signals to minimize EMI interference in industrial environments.

FAQ

Can I connect more than four of these modules to a single base unit?

No, the Series 90 Micro architecture supports a maximum of four expansion units connected in series to a single base PLC.

Is this module compatible with modern Windows-based programming software?

The IC693UEX122 is designed for use with Logicmaster 90-3/90-20 platforms and legacy hand-held programmers. Consult your specific software version documentation for compatibility with modern operating systems.
