Description
GE UR6AH High-Speed Digital I/O Module for Industrial Automation
The GE UR6AH is a versatile digital input/output (I/O) module designed for GE Multilin’s UR Series protective relays, delivering real-time control and monitoring in power generation, water treatment, and smart manufacturing. Optimized for harsh industrial environments, the UR6AH supports 16 isolated digital inputs (24–250 VDC/AC) and 8 solid-state outputs (0–250 VDC/AC), enabling seamless integration with sensors, actuators, and control systems.
1. Product Overview
The UR6AH acts as the “nervous system” of UR-series relay systems, converting analog signals into digital commands for automation processes. Its ±1% voltage accuracy and -40°C to +70°C operating range make it ideal for steel mills, wastewater plants, and offshore platforms. With hot-swap capability and Enervista UR configuration software, the module reduces commissioning time by 50% compared to legacy solutions in GE’s LM6000 gas turbines.

6. Selection Recommendations
- I/O Density: Choose UR6AH for 16 inputs/8 outputs; opt for UR6BH (32 inputs/16 outputs) for higher density.
- Harsh Environments: Use UR6AH in corrosive or high-vibration settings (e.g., chemical plants, mines).
- Budget: Refurbished units (GE-certified) save 35% while retaining 12-month warranties.
7. Installation & Maintenance Notes
- Wiring: Use stranded wires (18–22 AWG) for inputs/outputs; torque terminals to 2.5 N·m to prevent contact issues.
- Calibration: Factory-calibrated for 5 years; annual checks recommended for medical/pharmaceutical applications.
- Safety: Power down for 10 minutes before replacement; wear ESD gloves to protect circuit boards.
