GE Versamax Micro PLC Programmable Logic Controller 28 Point AC DC Relay IC200UEX211

GE Fanuc IC200UEX211-C VersaMax Micro Expansion Unit

Overview

The IC200UEX211-C belongs to the VersaMax Micro 28-point expansion unit family. Emerson’s VersaMax Micro product data sheet lists IC200UEX211 as a 28 point expansion with 16 × 24 VDC inputs, 12 relay outputs, and 120/240 VAC power supply.

A VersaMax Micro user manual chapter for IC200UEX211 further states that the unit accepts sixteen DC inputs, provides twelve normally-open 2 Amp relay outputs, and uses 100 to 240 VAC nominal input power.

The same manual describes the input circuits as configurable for positive or negative logic, identifies the relay outputs as Form A (SPST) normally open, and notes that the outputs can control field devices such as motor starters, solenoids, and indicators.

It also specifies a +24 VDC output power supply up to 200 mA for input circuits and user devices, plus AC power details including 50/60 Hz operation, hold-up time, and typical input current.

Technical Data

Application Value

This unit is suited to VersaMax Micro expansions in compact machine control, small automation panels, relay-output field interfaces, and systems that need additional 24 VDC inputs plus relay-driven outputs without replacing the existing VersaMax Micro base controller.

Its published 28-point combination makes it useful where the installation needs more field capacity but wants to stay inside the VersaMax Micro hardware structure.

The relay output structure also makes it practical in cabinets where the field side includes contact-driven devices such as starters, solenoids, or indicator loads.

The manual specifically identifies those types of loads, which helps define the product’s role in real control panels rather than only in abstract I/O terms.

Selection Notes

The main checks are the need for a 28-point VersaMax Micro expansion unit, the 16 × 24 VDC input / 12 relay output structure, the 120/240 VAC power-supply class, and the installed VersaMax Micro architecture.

These are the key compatibility points when replacing or expanding a system with IC200UEX211-family hardware.

FAQ

Q1: What kind of unit is IC200UEX211-C?
It is a VersaMax Micro 28-point expansion unit. Emerson’s product data sheet lists the IC200UEX211 as a 28-point expansion with 16 × 24 VDC inputs and 12 relay outputs, while the manual confirms its use as an expansion unit rather than a standalone CPU.

Q2: What is the practical meaning of 16 inputs and 12 relay outputs?
It means the module expands the VersaMax Micro system with a mixed I/O format: 16 digital field inputs and 12 contact-style outputs in one housing.

This combination is useful in compact machines where additional sensing points and relay-switched field loads are both required without dividing the expansion across multiple separate modules.

Q3: What kind of field loads can the relay outputs control?
The manual states that the twelve Form A normally open relay outputs can control devices such as motor starters, solenoids, and indicators.

It also specifies a 2 A switching capacity per circuit, which is one of the key published performance characteristics of the output side.

Q4: Why does the 120/240 VAC power-supply class matter?
Because the expansion unit is designed around that AC input class. The manual gives the nominal input power as 100 to 240 VAC, with published frequency and hold-up specifications, so the installed cabinet power arrangement should match that supply structure.

This is one of the first checks in replacement work.

Q5: What should be checked before ordering?
Check the installed part number, confirm the system uses the VersaMax Micro expansion architecture, verify that the application requires 16 × 24 VDC inputs and 12 relay outputs, and make sure the panel provides the correct 120/240 VAC power class.

Those are the key compatibility points for the IC200UEX211 family.
