GE Fanuc IC200UEX122-B

Product Overview

The GE Fanuc IC200UEX122-B is a 14-point VersaMax Micro PLC expansion unit designed to extend the I/O capability of compatible GE Fanuc automation systems. The IC200UEX122 family provides eight 24 VDC digital inputs and six transistor outputs, combining high-current and low-current output channels in one compact unit. GE documentation identifies the IC200UEX122 as a 14-point expansion unit with 24 VDC power and electronic short-circuit protection.

The module is well suited to compact machine-control applications where additional discrete I/O is required without installing a larger remote I/O station. The “-B” suffix identifies a specific hardware revision of the IC200UEX122 product.

GE's VersaMax Micro documentation specifies eight 24 VDC positive/negative-logic inputs and six transistor outputs, consisting of two high-current and four low-current channels.

I/O Configuration

One of the main advantages of the IC200UEX122-B is its mixed digital I/O arrangement. The eight input channels can receive signals from common industrial devices such as pushbuttons, limit switches, proximity switches, and other 24 VDC field sensors.

The six outputs are divided into two groups:

• Q1 and Q2: High-current transistor outputs
• Q3 to Q6: Low-current transistor outputs

The output circuits switch positive voltage and incorporate electronic short-circuit protection, eliminating the need for individual output fuses for this protection function. The outputs can also handle short-duration high inrush currents, making them suitable for loads such as lamps and certain inductive devices.

Design Features

The IC200UEX122-B is intended for compact control cabinets and distributed machine-control applications. Its integrated I/O arrangement reduces the need for separate input and output modules when only a moderate number of discrete points are required.

Important features include:

• Compact 14-point I/O configuration
• 24 VDC industrial input compatibility
• Positive and negative input logic
• Mixed high-current and low-current transistor outputs
• Electronic short-circuit protection
• Isolated field and logic circuitry
• Built-in isolated 24 VDC supply for input devices
• Compatibility with VersaMax Micro PLC architecture

The built-in isolated 24 VDC supply can provide power for input circuits and user devices, with the combined current requirement limited to 200 mA according to GE's documentation.

Typical Applications

The GE Fanuc IC200UEX122-B can be used in a wide variety of discrete automation applications, including:

• Packaging machinery
• Conveyor systems
• Material-handling equipment
• Machine tools
• Assembly equipment
• Factory automation
• Motor and actuator control
• Industrial production lines
• Compact process-control systems

Its combination of digital inputs and transistor outputs makes it particularly useful where sensors and discrete actuators need to be handled within the same compact PLC expansion unit.

Installation and Maintenance

When installing or replacing the IC200UEX122-B, technicians should verify the PLC configuration and field-wiring requirements before applying power. The supply should remain within the specified 19.2 to 30 VDC range, and output loads should remain within the applicable current ratings.

Recommended maintenance steps include:

1. Confirm the complete part number IC200UEX122-B.
2. Verify compatibility with the existing VersaMax Micro controller.
3. Check the 24 VDC power supply and polarity.
4. Inspect input and output wiring.
5. Confirm that output loads are suitable for transistor switching.
6. Check connectors for looseness or contamination.
7. Inspect the module for overheating or physical damage.
8. Verify I/O operation through the PLC program after replacement.

GE documentation also specifies 1500 V RMS isolation between the field side and logic side, providing an additional level of electrical separation between field circuitry and the controller electronics.

Spare Part Supply

The GE Fanuc IC200UEX122-B is a useful replacement component for facilities maintaining VersaMax Micro PLC systems. The exact part number is important when sourcing a replacement because similar IC200 expansion units can have different input voltages, output types, and power requirements.

The IC200UEX122-B is also listed by industrial automation suppliers as a VersaMax Micro 14-point expansion unit with 24 VDC power.

We supply GE Fanuc and GE automation spare parts, including VersaMax PLC modules, Micro expansion units, I/O modules, CPUs, communication modules, power supplies, and other industrial control components.
