GE Multilin UR6NH Universal Relay Series CT/VT Input Module
Configured for specific technical tasks in UR Series networks, the GE Multilin UR6NH (UR6NH CT/VT Input Module) provides direct physical/electrical execution. The module samples analog waveforms directly from external instrument transformers and transforms those potential and current fields into structured digital arrays. This hardware sub-component routes real-time data to the primary processor bus to manage protective threshold checking, fault sequencing, and metering calculations across generator, transformer, motor, and transmission line nodes.

Suffix Breakdown & Model Matrix
The UR6NH designation follows the standard architectural layout of the Multilin Universal Relay series modules, indicating its exact component assignment.
- UR: Universal Relay Series platform platform root identifier.
- 6N: CT/VT analog interface configuration indicator mapping internal channel counts.
- H: High-accuracy processing revision level block.
Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling
The UR6NH uses integrated analog-to-digital converters to match data transmission rates with backplane bus communication velocity limits. When scaling node data profiles during high-volume I/O density scaling adjustments, the card isolates field current and voltage lines to prevent cross-channel interference. This pathing permits local instrumentation data to map directly to external Profinet or EtherNet/IP deterministic networks via master bridge gateways. The card preserves strict firmware flash compatibility across legacy and current chassis variants, enforcing stable timing synchronization across all internal measurement registers.
Frequently Asked Questions
Q: Can the nominal current inputs on the UR6NH module be altered from 5 A to 1 A parameters under field conditions?
A: Yes. The current input channels support both 1 A and 5 A settings. Reconfiguration is executed through internal hardware tap jumpers combined with software setting selection inside the module software utility.
Q: Is it permissible to pull or replace the UR6NH card while the primary rack is powered up and live currents are traversing the CT loop?
A: No. Removing the module card from an active backplane disrupts processing bus lines and risks open-circuiting connected external current transformers. Open-circuit CT arrays generate high inductive voltage spikes that can destroy terminal insulation or cause severe electrical arcing.
Field Installation Guidelines
- Terminal Disconnection Sequence: Prior to removing or servicing the 0.7 kg module, verify that all external current transformer circuits are routed through shorting blocks and locked in a shorted configuration to prevent open-circuit loops.
- Module Alignment and Insertion: Insert the board into the designated track slots inside the UR casing frame. Apply continuous, steady horizontal pressure until the edge contacts lock completely into the rear backplane assembly, then tighten all front plate screws.
- Analog Ground Matrix: Ensure that the input transformer secondary shield drain lines hook up to the local master sub-station grounding grid at a single reference point to suppress low-frequency common-mode noise.
- Signal Cable Path Separation: Keep all high-voltage VT/CT instrumentation lines separated from low-voltage communication paths inside the wireways to eliminate inductive electromagnetic cross-talk.
