Product Description
The GE Multilin UR4DH is a high-density digital input/output expansion module dedicated to the GE Vernova UR universal relay series. This module integrates 8 configurable digital inputs and 4 isolated Form‑C relay outputs. It connects directly to the processor via the UR backplane, enabling microsecond-level signal transmission without additional couplers. It handles field signal exchange tasks including circuit breaker position feedback, disconnector status acquisition, alarm contact monitoring, and closing/tripping logic output.

FAQ
What is the maximum current that the Form-C contacts on a UR4DH can safely carry continuously?
The 4 Form-C relay contacts inside the UR4DH are rated to carry a continuous current of 10 A at a maximum voltage of 250 VAC / 250 VDC under resistive loads.
Can the output contacts of a UR4DH safely handle high-inrush currents during the initial fraction of a second of operation?
Yes, the UR4DH output circuitry features a high-inrush "Make & Carry" capability rated at 30 A for 0.2 seconds for tripping duty applications.
What is the exact scanning time resolution for the 8 digital inputs on a UR4DH module when recording a Sequence of Events log?
The UR4DH scans its digital inputs at an ultra-fast rate of 0.5 milliseconds (ms), ensuring millisecond-level precision for event tracking and interlocking logic.
Application
Thermal & Hydroelectric Power Plants: Deployed within generator protection, steam turbine control, and balance-of-plant (BOP) systems to monitor dense digital status points.
Petrochemical & Refinery Facilities: Installed in plant-wide substations and motor control centers (MCC) to ensure uninterrupted power distribution for critical continuous chemical processes.
Steel Mills & Metallurgical Plants: Integrated into high-voltage arc furnace power supplies and rolling mill distribution cabinets to execute high-speed digital interlocking commands.
Automotive & Heavy Manufacturing Assembly Plants: Utilized in main incoming substations to handle automated load-shedding schemes and monitor main grid tie-line switchgear statuses.
