GE IC200UDR005-BA Micro Controller

The GE Fanuc IC200UDR005-BA, also cataloged as the IC200UDR005BA Micro PLC Controller, operates as a dedicated hardware component for centralized logic processing and field I/O execution within GE VersaMax system platforms. The unit integrates a 32-bit microprocessor, internal AC power conversion circuitry, and fixed discrete terminal points into a single housing, allowing the internal CPU to read 16 DC input channels and drive 12 discrete relay outputs according to program logic.

Hardware Specifications

Backplane Bus Communication Velocity & Firmware Flash Compatibility

The internal processor manages serial communication over RS-232 and RS-485 interfaces, executing Modbus RTU Slave and SNP protocols without compromising scan time performance. Control engineers expand total I/O density scaling by attaching external VersaMax expansion modules through the dedicated expansion bus interface. Firmware flash compatibility across the expansion bus ensures synchronized data exchanges between the main CPU card and downstream I/O modules, which preserves real-time control execution across field networks.

Frequently Asked Questions

Q: How do field technicians configure communication protocols on the integrated RS-232 and RS-485 ports?

A: Engineers set communication parameters, node addresses, and protocol assignments (SNP Slave or Modbus RTU Slave) using VersaMax programming software over the primary serial port connection.

Q: What current limits apply to the integrated relay output channels?

A: Each relay output contact supports a maximum continuous load of 2 A per point; exceeding this rating requires external interposing relays to prevent contact welding.

Q: Does the unit support expansion I/O modules while operating from the primary AC supply line?

A: The internal power supply delivers logic power to the local processor and drives connected expansion modules up to the total backplane current limit of the expansion port.

Field Installation Guidelines

Ensure main power sources are de-energized prior to mounting or wiring the unit. Install the controller onto a standard 35 mm DIN rail or surface-mount using the integrated mounting holes. Wire field input and output lines directly to the fixed terminal block interface using recommended gauge copper conductors. Separate AC power lines from DC input cables and serial communication wiring. Terminate system ground connections to a low-impedance earth ground point on the panel baseplate to prevent electrical noise interference.
