Features

1. Power Supply Range: The UR-RLH operates within a nominal voltage range of 24 to 48 V DC, identified as a low voltage range module.

2. Critical Failure Relay Element: The module includes a form-C relay that energizes upon successful system boot, ensuring no self-test failures and proper control power application. It de-energizes in case of a critical failure during operation or loss of control power.

3. Battery Housing: The UR-RLH houses the battery for the Universal Relay, requiring removal and replacement during battery maintenance.

4. Compatibility: It is compatible with other modules in the Universal Relays series, such as the CPU module, CT/VT module, digital input/output module, transducer input/output module, and inter-relay communications.

Frequently Asked Questions

Q: What type of power supply is a General Electric UR-RLH UR series Multilin power supply?

A: The UR-RLH is a second-generation Multilin power supply module, designated as UR-RH. It replaced the first-generation modules (UR-1H). In 2014, the third generation (UR-SH) was introduced, designed to replace the earlier generations while maintaining compatibility with the same Universal Relays series.

Q: What type of voltage range does the UR-RLH power supply module have?

A: The UR-RLH has a low voltage range (24 to 48 V DC), as indicated by the ‘L’ in the part number. High power supply modules have voltage ranges of 125-250 V AC/DC for the first and second generations, and 125-300 V AC/DC for the third generation (UR-SH).

Q: What is the isolation voltage level for the UR-RLH GE Multilin power supply module?

A: For the second generation, the isolation voltage level is 2000 V AC, with an output power of 35 W. The third generation (UR-SH) modules have an increased isolation voltage level of 2300 V AC and an output power of 45 W.
