The GE Multilin UR-6CH Digital I/O Module is a critical component in industrial automation and protection systems,
primarily designed for integration with GE Multilin protective relays (e.g., UR series).
Below are its key functions and applications:
1. Key Functions of the UR-6CH Digital I/O Module
Digital Signal Processing:
Provides 16 digital inputs and 8 relay outputs for monitoring and controlling industrial equipment.
Supports dry/wet contact inputs (24–250V AC/DC) and form-C relay outputs (5A, 250V AC).
Integration with Protection Relays:
Expands the I/O capacity of Multilin UR-series relays (e.g., UR6xx) for enhanced system scalability.
Enables real-time status monitoring (e.g., breaker position, alarm signals) and remote control.
Industrial Durability:
Designed for harsh environments with wide temperature tolerance (-40°C to +85°C) and high EMI resistance.
Complies with IEC 61850 and Modbus protocols for seamless SCADA/EMS integration.
Flexible Configuration:
Programmable via EnerVista UR Setup software for custom logic and automation rules.
2. Typical Applications
Power systems:
Breaker control, fault indication, and load shedding in substations.
Industrial automation:
Machine safety interlocks and process control.
Renewable energy:
Wind/solar farm grid integration and fault management.
This module ensures reliable, high-speed signal processing in critical infrastructure.
