Features:
- Combines sixteen 120 VAC inputs with twelve relay outputs in one 28-point controller.
- Provides RS-232 and RS-485 communication interfaces for programming and serial devices.
- Retains program and clock-dependent control data through battery-backed resources.
General Electric IC200UAR028 suits compact machines that receive line-voltage status signals and must switch a mixture of compatible AC or DC loads.
Relay contacts keep output load selection flexible, while electrical grouping and protective devices should be planned for each field circuit.
The Micro 28 platform can add four expansion modules, giving the controller room to accommodate later I/O changes without replacing the base unit.
The General Electric IC200UAR028 28-Point VersaMax Micro PLC may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

AC Input and Relay Architecture
- Input Channels: The sixteen input points read 120 VAC field states used by switches, limit devices, and interposing contacts.
- Relay Outputs: Twelve relay output points provide dry-contact switching for compatible AC or DC control loads.
- Circuit Commons: Input and output commons must follow the controller terminal grouping to preserve the intended circuit separation.
- Branch Protection: External protection should match the conductor size, load type, and relay contact rating of each branch.
Program Retention and Clock Functions
- Logic Capacity: Nine thousand words of logic memory accommodate sequencing, interlocks, and machine-control routines.
- Data Storage: Two thousand words of data storage retain operating values needed by the application.
- Clock Function: A real-time clock supports scheduled events and timestamp-dependent control logic.
- Retention: The battery and supercapacitor arrangement protects retained resources during normal power interruptions.
Programming and Device Communication
- RS-232 Interface: The RS-232 interface provides a direct path for programming or a compatible point-to-point device.
- RS-485 Interface: The RS-485 interface supports longer multidrop serial arrangements when the selected protocol permits them.
- Port Parameters: Port parameters in PAC Machine Edition must match the baud rate, framing, and protocol of connected equipment.
- Network Wiring: Cable shielding, termination, and grounding should be chosen for the electrical environment and network length.
Suitable Control Tasks
- Packaging Equipment: Packaging equipment can combine 120 VAC sensor states with relay-driven solenoids, contactors, or pilot devices.
- Material Handling: Material-handling cells can execute interlocks locally while exchanging status with a serial operator interface.
- Utility Skids: Utility skids can use clock functions for periodic sequences and retain process settings through shutdowns.
- Panel Expansion: Small machine panels can expand beyond the built-in 28 points by adding compatible VersaMax Micro modules.
