Description
Product Introduction & Engineering Value
When high-density I/O is required in a tight panel footprint without the cost and complexity of a modular rack system, the GE VersaMax Micro IC200UDR064 stands out as a high-capacity all-in-one controller. Housing a 32-bit RISC processor, 64 integrated I/O points, and a 24 VDC system power supply inside a compact 190 mm wide DIN-rail chassis, this unit eliminates the need for separate CPU, backplane, and I/O carrier cards.
The IC200UDR064 bridges the gap between micro-controllers and full rack PLCs by providing 40 DC inputs and 24 electro-mechanical relay outputs. It supports up to 4 additional VersaMax expansion units (extending physical I/O up to 176 points) and includes built-in high-speed counters for positioning tasks. It is an ideal drop-in controller for packaging, material handling, and small OEM machinery applications.

Field Application & The “Trench” Experience
During an emergency retrofit on a pharmaceutical cartooning line, an older micro-controller failed due to an output coil short. The customer needed to replace the failed unit while retaining dry-contact relay isolation for 24VAC solenoid valves and 24VDC status stacklights. We deployed an IC200UDR064 because its 24 relay outputs offer isolated contacts rated for both AC and DC voltages up to 2A per point.
By using Proficy Machine Edition (or legacy VersaPro), the logic was ported quickly. The unit’s removable terminal strips saved over two hours of re-wiring time, allowing field maintenance to drop the pre-wired terminal blocks straight onto the replacement controller.
Niche Application Scenarios:
- Material Handling & Conveyors: Utilizing built-in high-speed inputs (100kHz) for optical encoder tracking and photo-eye package counting.
- Standalone OEM Skids: Managing pump stations, water filtration panels, or small HVAC air handlers operating off a 24VDC control transformer.
- Mixed Voltage Switching Panels: Applications where 24VDC sensors share the panel with mixed 120VAC actuators requiring isolated relay contacts.

Transparency SOP: QA & Testing
To guarantee every New Surplus or Refurbished IC200UDR064 performs reliably in mission-critical applications, each unit passes a 5-step hardware audit:
- Terminal Strip & Housing Inspection: Physical check of DIN-rail spring clips, connector pins, LED lens covers, and removable terminal block screws.
- 24VDC Power Supply Regulation Test: Sweeping input power from 18 VDC to 30 VDC under load to ensure internal 5V/3.3V logic rails remain within ±1%.
- 40-Point DC Input Loop Testing: Exercising all 40 discrete input channels using a simulated field switch bank to verify optocoupler isolation and LED status toggling.
- 24-Point Relay Contact Load Test: Actuating all 24 relay outputs against a 2A resistive load bank to ensure relay contacts pull in cleanly with low contact resistance (<0.1 Ohm).
- HSC & Serial Communications Audit: Driving a 100 kHz pulse stream into HSC Channel 1 while performing program uploads and downloads via Port 1.
The Veteran’s Tech Trap Guide
- ⚠️ Check the Model Prefix (UDR vs UDD vs UAA): The features Relay outputs. Do not confuse it with the IC200UDD064 (which features transistor 24VDC solid-state outputs). Transistor models support high-speed Pulse Train Outputs (PTO) for stepper drives, whereas relay outputs (UDR) cannot toggle fast enough for PTO motion profiling.
- PRO TIP: Mind the Power Supply Wiring! The requires a 24 VDC main power supply. If your panel only supplies 120/240 VAC power, you must select the IC200UDR164 model instead. Applying 120 VAC to the power terminals of an will instantly burn out the primary power stage!
- ⚠️ Relay Contact Inductive Suppression: When switching inductive AC or DC loads (such as solenoid valves or motor contactor coils), always install external RC snubbers (for AC) or freewheel diodes (for DC) across the load. Unsuppressed inductive kickback will pit and weld the relay contacts over time.
Dynamic FAQ
Q: What programming software is required for the ?
A: The controller can be programmed using Proficy Machine Edition (ME) (version 5.5 SP2 SIM5 or later) or legacy VersaPro software via an RS-232 serial cable connected to Port 1.
Q: Can I add analog inputs/outputs to this Micro controller?
A: Yes. You can attach up to 4 VersaMax Micro Expansion units (e.g., analog expansion modules) to the expansion port on the right side of the unit.
Q: Does the retain user programs during power outages?
A: Yes. Logic programs and configuration are stored in non-volatile flash memory. An optional plug-in battery back-up module maintains real-time clock and internal data registers during extended shutdowns.
Q: What warranty is provided on supplied units?
A: All inspected and fully tested units come backed by a comprehensive 1-Year replacement warranty.
