GE UR 6CH – Multilin Universal Relay | GE Multilin UR Series Protection Platform
Engineering Background
The GE Multilin UR Series represents GE Grid Solutions’ flagship platform for universal protection, control, and monitoring of power system assets. Designed for utility-grade and industrial substation environments, the UR platform delivers IEC 61850-compliant communications, high-speed protection algorithms, and modular I/O architecture in a single, standardized chassis. The UR 6CH is a specific I/O or communications module within this platform, engineered to extend the relay’s channel capacity and integration capability.
Product Positioning
The UR 6CH module is targeted at protection engineers and substation automation specialists who require deterministic, high-integrity signal handling within GE Multilin UR-series relay systems. It is the preferred choice for greenfield substation builds, protection scheme upgrades, and legacy system modernization projects where GE Multilin compatibility is mandatory.

Engineering Advantages
System Architecture & Signal Flow
The UR 6CH module integrates into the UR chassis backplane, interfacing directly with the UR CPU module via the internal high-speed bus. Signal flow within the UR platform follows a deterministic, interrupt-driven architecture:
The UR 6CH module’s role within this architecture is to extend the available channel count (analog inputs, digital inputs, or output contacts) beyond the base chassis configuration, enabling protection engineers to implement complex multi-function schemes within a single UR chassis.
Sourcing & Quality Verification
Konmask.com operates a structured 4-step verification process for all GE Multilin UR series modules:
All units are shipped in ESD-safe packaging with humidity indicators. Traceability records are retained for a minimum of 5 years.

Technical FAQ
Q: Is the UR 6CH compatible with all UR chassis sizes?
A: The UR 6CH is designed for the GE Multilin UR modular chassis. Compatibility depends on the specific chassis model and slot configuration. Please provide your chassis model when inquiring to confirm fit.
Q: Can the UR 6CH be field-replaced without relay reconfiguration?
A: In most UR platform configurations, module replacement requires re-downloading the relay settings file via EnerVista software. Konmask.com can provide guidance on the replacement procedure.
Q: What firmware version does the supplied unit carry?
A: Firmware version varies by unit. We will confirm the firmware version during the quotation stage and can advise on upgrade paths if required.
