The UR6CH is a dedicated digital input/output expansion module purpose‑built for GE Multilin‘s Universal Relay (UR) series. When the host relay’s native I/O capacity falls short, the UR6CH seamlessly integrates into the UR chassis backplane to deliver eight Form‑C (SPDT) relay outputs. Each UR6CH output functions as a changeover contact, selectively switching between normally‑open and normally‑closed states to command external actuators, solenoid valves, contactors, and annunciator panels. The UR6CH supports seamless integration with UR protection relays (UR‑1H through UR‑9H) and is fully configurable via EnerVista UR Setup software, making it an ideal solution for expanding control points in power protection and industrial automation systems without redesigning the entire control cabinet.

Retrofit and upgrade of legacy control panels using GE UR relays
8 Form‑C (SPDT) relay outputs: Each channel is an independent changeover relay that switches its common terminal between normally‑closed (NC) and normally‑open (NO) contacts.
High contact current rating: Supports 5 A resistive loads (250 V AC / 30 V DC) and 2 A inductive loads — suitable for directly driving contactors and solenoid valves.
Direct chassis integration: Plugs into the UR relay backplane slot without requiring additional cabling or external power supplies (logic power derived from the chassis).
FlexLogic‑compatible output mapping: Output states are fully programmable via EnerVista software, allowing users to map any internal protection element or logic operand to each Form‑C contact.
Hot‑swappable design: The module can be inserted or removed while the UR relay remains powered, minimizing downtime during maintenance and system upgrades.
Electrical isolation: Output contacts are galvanically isolated from the relay logic, eliminating ground‑loop interference and protecting sensitive control electronics.
Wide operating temperature range (–40°C to +85°C): Engineered to withstand extreme thermal conditions, vibration, and electrical noise present in power generation and heavy industrial environments.
LED per‑channel status indication: Each output has a dedicated LED that illuminates when the contact is energized, simplifying on‑site troubleshooting.
EnerVista software support: Module configuration, contact mapping, and diagnostics are managed through the same intuitive software interface as the host UR relay.
Backplane communication: Exchanges data with the UR CPU via high‑speed protocols (IEC 61850, Modbus, DNP3), enabling deterministic state updates with < 10 ms response time.
Expands the host UR relay‘s physical I/O count by providing eight additional Form‑C changeover outputs for field connection.
Executes relay trip commands or control logic outputs generated internally by FlexLogic and transmits them as physical contact closures.
Switches each Form‑C contact between normally‑open (NO) and normally‑closed (NC) states based on programmed logic from the UR CPU.
Monitors output channel status through onboard LEDs and reports diagnostic conditions (contact stuck, open circuit) back to the UR CPU over the backplane.
Electrically isolates field output circuits from the relay‘s internal low‑voltage logic to withstand high‑voltage transients and surges.
Supports deterministic output activation with ≤ 10 ms response time, ensuring timely execution of protection trips and control commands.
Provides universal compatibility with UR‑1H through UR‑9H series relay chassis, allowing flexible system configuration.
Receives configuration data via backplane communication and stores it in non‑volatile memory; settings persist through power cycles.
Drives up to 5 A resistive load per contact, enabling direct control of solenoid valves, indicating lamps, contactor coils, and small motors.
Serves as a central signal distribution point for interlocking multiple auxiliary devices from a single UR protection relay chassis.
Q1: What is the primary function of the UR6CH module?
A1: The UR6CH is a digital I/O expansion module that adds eight Form‑C (SPDT) relay outputs to GE Multilin UR series protection relays, expanding system capacity without altering the original relay configuration.
Q2: How many output channels does the UR6CH provide?
A2: The UR6CH provides eight relay output channels. Some supplier listings may reference additional digital input channels, but the core function of this module is 8× Form‑C relay outputs for the UR series backplane.
Q3: What type of output contacts does the UR6CH use?
A3: The UR6CH uses Form‑C (SPDT) changeover contacts. Each Form‑C output has a common terminal that connects to either a normally‑closed (NC) or normally‑open (NO) contact, allowing the user to select the desired output behavior in the application.
Q4: Is the UR6CH hot‑swappable in a running UR relay system?
A4: Yes, the UR6CH is designed for hot‑swappable installation, meaning it can be inserted or removed while the UR relay remains powered, significantly reducing system downtime during maintenance or upgrades.
Q5: Which GE Multilin products are compatible with the UR6CH ?
A5: The UR6CH is compatible with GE Multilin UR series universal relays (including UR‑1H through UR‑9H chassis). It installs into an available backplane slot and is configured through EnerVista UR Setup software.
