Deterministic Network and I/O Scaling Characteristics

The UR-5DH module provides programmable transducer processing within the GE Universal Relay architecture. The four RTD input channels acquire resistance values directly from field temperature sensors connected to transformer windings, motor stators, bearing assemblies, or ambient measurement points.

The four DC milliamp outputs convert internal relay measurements into proportional analog signals for connection to legacy SCADA systems, RTUs, DCS input cards, or panel instrumentation. The module supports configurable output scaling through GE EnerVista UR Setup software.

The module architecture supports I/O density scaling within the UR relay platform by adding dedicated analog acquisition and output channels without external signal conversion hardware.

Frequently Asked Questions

Q: Does the UR-5DH require external RTD transmitters for temperature measurement?
A: No. The module accepts direct RTD resistance inputs from compatible field sensors and transfers the measured values into the relay thermal monitoring functions.

Q: Are the DC milliamp outputs electrically isolated?
A: Yes. The module provides galvanic and optical isolation between channels and the system ground according to the module design specifications.

Q: Can the analog outputs be configured for different current ranges?
A: Yes. The DC milliamp outputs are programmable for ranges including 0-1 mA, 0-5 mA, 0-10 mA, 0-20 mA, and 4-20 mA.

Field Installation Guidelines

Install the UR-5DH module into the designated expansion slot of the GE Universal Relay chassis while observing the relay installation procedure.

RTD field wiring should use appropriate instrumentation cable routing practices. Keep sensor wiring separated from high-current power conductors to reduce electromagnetic interference. Shielded cable termination should follow the grounding requirements defined for the connected relay system.

Verify terminal connections for RTD polarity, sensor type configuration, and output loop wiring before energizing the module. Configure RTD parameters and analog output scaling through EnerVista UR Setup software after hardware installation.
