General Electric IC200UAR028 VersaMax Micro 28-Point PLC Controller

Description

The General Electric IC200UAR028 is a 28-point micro programmable logic controller from the VersaMax Micro platform, engineered for standalone industrial machinery, utility skid automation, and distributed control tasks. Powered by a 120/240 VAC line supply, this compact all-in-one controller integrates discrete AC inputs, relay outputs, CPU logic execution, and serial communications within a single DIN-rail or panel-mounted unit.

The unit features 16 reactive 120 VAC discrete inputs and 12 Form A relay outputs divided across two current capacities: two 10 A relay circuits designed to switch heavier inductive or resistive field loads, and ten 2 A relay circuits intended for general pilot devices, motor starters, and visual indicators. The controller provides 9 K words of user program logic memory and 2 K words of register data space for standard ladder and logic execution.

Onboard communications comprise two physical serial channels: Port 1 provides an RS-232 connection through an RJ-45 jack, while Port 2 offers an RS-485 interface via a 15-pin D-sub connector. For applications requiring capacity beyond the base 28 points, the IC200UAR028 interfaces with up to four VersaMax Micro expansion units, enabling expansion up to a maximum of 140 physical I/O points.

Features

• 28 embedded I/O points: 16 discrete AC inputs and 12 Form A relay outputs
• Split-capacity relay staging: two 10 A contacts and ten 2 A contacts
• Integrated power supply supporting 100 to 240 VAC nominal line power at 50/60 Hz
• Dual serial ports: Port 1 (RS-232 on RJ-45) and Port 2 (RS-485 on 15-pin D-sub)
• Expansion bus supporting up to 4 VersaMax Micro discrete or analog expansion modules
• Integrated real-time clock and dual onboard potentiometers for manual analog setting
• Direct installation onto standard 35 mm DIN rail or flat backpanel

Configuration Guidelines

• Configure and program the unit using VersaPro 1.1 or higher, or Proficy Machine Edition Logic Developer PLC.
• To protect user program data and preserve real-time clock values during system power cycles, install the IC200ACC403 lithium battery while input power is switched off.
• Connect compatible VersaMax Micro discrete or analog expansion modules to the right-side expansion port to expand system capacity up to 140 physical I/O points.
