GE VersaMax IC200UAR028 Micro Controller Processor

Product Overview

The IC200UAR028 is a high-performance Micro Controller Processor from the GE Fanuc VersaMax series, designed to provide compact yet powerful control for mid-sized industrial applications. This 28-point PLC is equipped with 16 dedicated 120 VAC inputs and a flexible array of 12 relay outputs (comprising 4 high-current 10 Amp relays and 8 standard 2 Amp relays). Operating on a 120/240 VAC power supply, it features 2 MB of memory capacity to handle complex logic and data processing. With its wide operating temperature range and integrated RS-232/RS-485 communication ports, the IC200UAR028 offers a reliable, made-in-USA solution for distributed control and machine-level automation.

Technical Specifications

Engineering Advantages

• High-Current Relay Options: Unlike standard micro PLCs, this unit includes four 10 Amp relays, allowing for the direct control of heavier loads without external interposing relays.
• Substantial Memory Reserve: With 2 MB of memory, it supports extensive user programs and data logging, ensuring the controller can scale with system requirements.
• Dual Protocol Support: Integrated RS-232 and RS-485 ports facilitate easy connection to HMIs, programming terminals, and multi-drop peripheral networks.
• Rugged Environmental Spec: Tested for operation down to -20 °C, making it suitable for unconditioned control cabinets and outdoor industrial enclosures.

Installation & Maintenance

For data retention and real-time clock stability during power outages, the IC200UAR028 requires the IC200ACC403 battery (sold separately). When wiring the 120 VAC inputs, ensure proper isolation between power and signal lines to minimize noise. The unit should be mounted in an upright position to allow for natural convection cooling across its operating temperature range. Regular maintenance should include checking the battery status LED and ensuring terminal screw tightness in high-vibration environments.

Technical FAQs

Q1: Does this PLC support expansion?
A1: Yes, the VersaMax Micro series is modular, allowing for additional I/O expansion modules to be connected to the main CPU to increase point counts as needed.

Q2: Can I program this unit via the RS-232 port?
A2: Absolutely. The RS-232 port is the standard interface for connecting a PC running Proficy Machine Edition or VersaPro for configuration and troubleshooting.

Q3: What is the benefit of the 120 VAC input rating?
A3: This allows for direct interfacing with standard industrial switches and sensors powered by the AC mains, eliminating the need for 24 VDC power supplies for simple control circuits.
