Product Overview

The GE UR 6PH Multilin UR Series Digital I/O Module is an interface module used with GE Multilin Universal Relay (UR) systems to handle discrete field signals. It connects external digital devices to the relay platform, allowing status inputs and control outputs to be incorporated into protection, monitoring, and automation functions.

In a UR installation, digital I/O modules are typically used for signals such as breaker status, trip circuit supervision, interlocking, alarms, auxiliary contacts, and control commands. The 6PH module expands the relay’s field interface capability while allowing these signals to be incorporated into the configured protection and control logic.

For replacement applications, the complete module designation should be matched with the installed UR relay configuration. The terminal arrangement, I/O assignment, and relay firmware configuration should also be checked before commissioning.

Product Features

  • Digital I/O interface for GE Multilin UR Series relay systems.
  • Supports integration of discrete field signals into relay protection and control schemes.
  • Suitable for breaker status, auxiliary contacts, alarms, interlocking, and control circuits.
  • Expands the field-level interface capability of a UR relay.
  • Supports system-level monitoring and control functions through the UR platform.
  • Suitable for maintenance replacement and existing relay system refurbishment.

Working Principle

The UR 6PH receives discrete signals from external field devices and makes those signals available to the UR relay’s configured logic. Output channels operate in the opposite direction, allowing relay logic to issue discrete commands to external control equipment.

A simplified signal path is:

Field Contacts / Control Devices → UR 6PH Digital I/O Module → UR Relay Logic → Protection / Control Functions

For an input signal, the module detects the electrical state of the connected field circuit and transfers the corresponding digital status to the relay. The UR relay can then use that status in protection logic, programmable logic, alarms, measurements, or control sequences.

For an output command, the relay logic determines the required state and sends the corresponding discrete output through the module to the connected field circuit.


Role in a Multilin UR Series Protection and Control Architecture

System Element Function
Circuit Breaker / Switchgear Performs switching and provides auxiliary status signals
Field Contacts Provide discrete status and alarm information
GE UR 6PH Interfaces digital field signals with the UR relay
Multilin UR Relay Executes protection, control, monitoring, and programmable logic
Protection CTs / VTs Provide electrical measurements for protection functions
Trip / Close Circuits Receive discrete control commands
SCADA / Station Network Provides higher-level monitoring and control

The 6PH module sits at the field-interface level of the UR architecture. Its signals can become inputs to the relay’s programmable logic or outputs from that logic to external control circuits.


Industrial Applications

Application Typical Use
Substation Protection Breaker status, alarms, interlocking, and control signals
Switchgear Digital monitoring and breaker control interfaces
Generator Protection Auxiliary contacts and equipment status monitoring
Transformer Protection Alarm and auxiliary signal integration
Motor Protection Contactor, breaker, and equipment status signals
Industrial Power Distribution Discrete control and monitoring within electrical protection systems
Retrofit Projects Replacement or expansion of digital I/O capability in existing UR installations

Installation and Maintenance

  1. Confirm the complete UR 6PH module designation before installation.
  2. Isolate the relay and associated field circuits according to the site’s electrical safety procedure.
  3. Record the existing terminal connections and I/O assignments before removing the installed module.
  4. Verify that the replacement module matches the UR relay hardware configuration.
  5. Inspect terminal blocks, connectors, and field wiring for damage or loose connections.
  6. Check the external circuit voltage against the requirements of the corresponding digital I/O channels.
  7. Install the module in the correct UR relay position.
  8. Reconnect each field circuit according to the original wiring documentation.
  9. Verify input polarity and output circuit connections before energizing the equipment.
  10. Restore power and check the UR relay for module or configuration-related diagnostics.
  11. Test representative digital inputs and outputs from the field side and confirm the expected relay status.
  12. Confirm protection, control, alarm, and interlocking functions before returning the relay to normal service.

Technical FAQs

What types of signals can the UR 6PH handle?

The UR 6PH is a digital I/O module intended for discrete field signals. Typical applications include breaker auxiliary contacts, alarms, interlocks, equipment status signals, and discrete control commands.

How does the UR 6PH interact with the Multilin UR relay?

Digital inputs from the module are made available to the UR relay’s configured logic. Relay logic can use these states for protection, control, alarms, and automation functions, while configured digital outputs can transmit commands to external circuits.

What should be verified when replacing a UR 6PH module?

The complete module designation, relay hardware configuration, terminal assignment, field wiring, I/O configuration, and applicable firmware or configuration requirements should be checked. The replacement should match the existing UR system configuration before it is commissioned.

What should be tested after installing the module?

Verify the module is recognized by the relay, then test the relevant digital inputs and outputs from the field circuit. Confirm breaker status, alarms, interlocks, trip/close commands, and other application-specific logic respond as expected before placing the protection system back into service.
