The GE UR6EH plug-in card gives any Universal Relay (UR) chassis eight true high-voltage digital inputs. Breaker auxiliary contacts, disconnect switches, spring-charge and gas-pressure flags can be wired straight to the UR6EH terminals—no interposing relays, no extra panel depth—while 2 kV optical isolation and <2 ms pick-up time keep protection logic and SOE records sub-cycle accurate.

Typical Wiring
Field dry-contact → UR6EH Euro-style terminal → on-board limiting → opto-coupler → UR bus. Self-resetting PTCs protect the circuit from surge or mis-wire; LED per channel gives local status at a glance.
Where It Fits
1. Substation automation: 220 V breaker position, lock-out relay and gas-low flags wired direct to UR6EH; CPU runs protection, metering and SOE in one box.
2. Generation plants: exciter ready, field-breaker and synchronizer selector voltages up to 380 V feed the same card, eliminating rows of 110 V interface relays.
3. Oil & gas topside: 380 V main-tie contactor auxiliaries drive emergency-shutdown logic through UR6EH with <2 ms update.
