Product Overview
The GE Multilin UR6NA functions as a high-density, slide-in Digital Input/Output (I/O) expansion module designed specifically for the Multilin Universal Relay (UR) platform. This module serves as the primary hardware interface connecting protection relays to high-voltage circuit breakers, emergency alarm panels, and external signaling equipment. Substation engineers deploy this card to execute complex programmable automation logic, hardware interlocking sequences, and real-time trip commands.
The hardware interfaces directly with the central relay processor bus to coordinate high-speed signal distribution across generator, transformer, motor, and transmission line protection frameworks. It integrates optical isolation circuits to screen out hazardous electrical surges common to electrical power systems.
We deliver this protection relay component exclusively in 100% brand new, original, and factory-sealed condition. This guarantees pristine contact surfaces on the output relays, undamaged internal optocouplers, and complete operational lifetimes inside critical utility protection enclosures.

Engineering Advantages
- Optically Isolated Input Protection: Internal optical couplers electrically isolate the nominal 24 VDC digital input channels from the sensitive CPU board. This layout stops severe high-voltage spikes, lightning surges, and induced ground loop currents from damaging the core protection processor.
- Heavy-Duty Form-C Tripping Output: The integrated Form-C relay contacts switch up to 8 Amps at 250 VAC or 30 VDC continuously. This high current capacity allows the module to drive heavy circuit breaker trip coils and inductive auxiliary relays directly, removing the need for external interposing relays.
- Complete Hardware Galvanic Isolation: Galvanic separation barriers divide each individual I/O channel path from the interior logic bus lines. This structural design isolates inductive noise generated by field-level contact bounce, ensuring clean status registration inside the relay logic tables.
- Utility-Grade Environmental Hardening: Premium industrial component sourcing allows the module to withstand an extended thermal operating window spanning from -40 up to +70 degrees Celsius. This design ensures uninterrupted performance inside unheated remote substation buildings and desert control cubicles.
FAQs
- Is this UR6NA digital I/O module a brand new original factory piece?
- Yes. We distribute the UR6NA module exclusively as a 100% brand new, original, authentic factory-sealed unit. It ships directly in its original unopened manufacturer packaging to confirm that the internal relay contacts have never sustained field-level arcing or electrical stress.
- Which protective relay families within the GE Multilin series accept this I/O module?
- The UR6NA module maintains universal structural compatibility across the entire GE Multilin UR family. This allows you to insert the card into any matching open slot on generator protection relays (G60), transformer protection units (T60), feeder management relays (F60), or motor protection controllers (M60).
- Can I configure the digital inputs to respond to AC voltage controls instead of DC lines?
- No. The input channels on this specific UR6NA hardware version utilize internal optocoupler configurations calibrated for a nominal 24 VDC threshold. Introducing high-voltage AC lines directly into these terminals will damage the internal conditioning circuits.
- Does this card require separate field-side grounding terminations during installation?
- The module grounds its internal shield planes automatically through the heavy chassis guidance rails upon insertion into the primary UR rack casing. You must ensure that your external field signal cables utilize proper shielding methods and terminate at the master panel ground bar to maintain high electromagnetic compatibility.
