Description

The UR6AH is a digital I/O expansion module engineered by GE Multilin for the Universal Relay (UR) platform. This UR6AH module provides extended digital input and output capacity, enabling UR series protective relays to interact seamlessly with field devices such as circuit breakers, disconnect switches, pushbuttons, indicator lights, and solenoid valves. Serving as an auxiliary I/O interface, the UR6AH collects contact status signals from substation equipment and drives trip/close commands to actuators, expanding the relay’s monitoring and control reach without requiring standalone PLCs or RTUs. The UR6AH features high‑density Form‑C relay outputs with generous contact ratings, galvanic isolation, independent channel LEDs, and programmable logic for local interlocking and sequencing. Configurable via Enervista UR software and compliant with IEC 61850 standards, the UR6AH integrates smoothly into modern digital substation architectures and industrial automation systems, reducing hardware footprint and lifecycle costs while enhancing system reliability.

Applications

Substation automation – circuit breaker position monitoring, disconnect switch status acquisition, trip/close command execution
Transmission and distribution networks – feeder protection, recloser control, bay‑level interlocking
Transformer protection – differential protection backup, on‑load tap changer (OLTC) control
Generator protection – unit auxiliary contact monitoring, excitation system interlocking
Motor protection – starter contactor control, pump and fan sequencing for large three‑phase motors
Bus protection schemes – high‑impedance bus differential logic, lockout relay triggering
Industrial power systems – process interlocking, alarm annunciation, emergency shutdown (ESD) I/O
Renewable energy facilities – inverter status monitoring, breaker control in solar and wind farms

Features

High‑density I/O expansion – adds up to 16 digital inputs and 16 Form‑C relay outputs to UR series relays, reducing the need for auxiliary PLCs or RTUs
Wide‑range input compatibility – accepts 24–250 VDC or VAC dry/wet contact signals with programmable digital filtering for noise immunity
Robust output capacity – Form‑C (SPDT) relays rated at 8 A / 250 VAC or 30 VDC, suitable for driving trip coils, contactors, and solenoid valves
Complete galvanic isolation – 2500 VAC isolation between channels and system, with independent opto‑isolation on inputs and coil‑to‑contact isolation on outputs
Onboard diagnostic LEDs – independent status indicators for each input and output channel for real‑time visual monitoring and rapid fault localization
Plug‑and‑play integration – direct backplane connection to UR series chassis; no external power supply or discrete wiring needed
Event sequence recording (SOE) – captures input state changes with ≤1 ms resolution for post‑event analysis
Programmable output logic – per‑output setpoint logic (AND/OR), pulse stretching, and delay timers configurable via Enervista UR Setup software; no hardware jumpers required
Extreme environment readiness – conformal‑coated PCB rated for –40°C to +85°C operation, compliant with IEC 60255-21 vibration/shock standards

Functions

I/O capacity extension – adds configurable digital input and output channels to UR series relays beyond their built‑in I/O count
Field status acquisition – captures dry contact or voltage signals from circuit breaker auxiliary contacts, position switches, and pushbuttons
Protection command execution – drives trip and close commands to breaker trip coils, lockout relays, contactors, and indicating lights based on relay protection logic
Local programmable logic – executes setpoint‑based interlocking, sequencing, and pulse stretching independently of the main relay processor
Diagnostic and event logging – provides SOE timestamping and LED channel status for maintenance and post‑fault analysis
Signal isolation – electrically isolates field wiring from the UR relay internal electronics to protect sensitive control circuits

FAQ

Q1: What is the UR6AH used for?
A1: The UR6AH is a digital I/O expansion module for GE Multilin UR series protective relays, adding extra input and output channels for monitoring field device status and controlling breakers, contactors, and alarms.

Q2: Does the UR6AH require an external power supply?
A2: No. The UR6AH draws all necessary operating power directly from the UR series chassis backplane; no separate external power supply is needed.

Q3: How many inputs and outputs does the UR6AH provide?
A3: The primary UR6AH variant offers 16 digital inputs and 16 Form‑C (SPDT) relay outputs. Alternative configurations (e.g., 8 inputs + 2 outputs) may also be encountered depending on the specific SKU.

Q4: What software is used to configure the UR6AH?
A4: The UR6AH is configured using GE’s Enervista UR Setup software, which allows users to program input filtering, output logic (AND/OR, timers, pulse stretching), and setpoint assignments without hardware jumpers.

Q5: Which UR series relays are compatible with the UR6AH?
A5: The UR6AH is compatible with all UR series main devices that support expansion modules, including UR9AH, UR7AH, UR5AH, UR60, UR80, and UR100, provided the chassis has an available backplane slot.
