Product Introduction

The GE Multilin URRHH (also known as UR-RHH) is a power module designed for integration with GE Multilin's Universal Relay Series. The module plays a vital role in powering the relay itself as well as powering the dry contact input connections.

Dual Voltage Option: Two voltage range options are available - Low Range (LO) operates from 24 to 48 V nominal (DC only) and High Range (HI) operates from 125 to 250 V nominal (DC and AC compatible)

Redundant Power Supply Option: Available with or without redundant power supply capability for enhanced system reliability.

Internal Fuse Rating: Equipped with a 4A/250V internal fuse rating to ensure safe and reliable operation under a wide range of conditions.

Self-Test Mechanism: Built-in self-test mechanisms are used to regularly evaluate the health and functionality of the power module. These tests (primary and secondary) are critical to verifying the integrity of the device and can remove power from the power module in the event of a critical fault.

LED Indicators: Communicate the status and potential problems of the power module using LEDs located on the faceplate of all UR devices, including indicators for continuous on, on/off cycle, and off status.

The GE Multilin URRHH Power Module is an important part of the Universal Relay family, providing a robust power solution to meet the needs of a wide range of industrial applications. Its features, including dual voltage options, self-test mechanisms, and LED indicators, enhance its reliability and ease of use, making it an excellent choice to enhance relay-based control systems.

GE's UR-RHH is a power module designed to be installed within the Universal Relay family. The module is available in two voltage ranges and can include or exclude redundant power supply options. The low range (LO) operates from 24 to 48 V (DC only), while the high range (HI) operates from 125 to 250 V (DC and AC). The power module is capable of powering the relays as well as the dry contact input connections. The power module's internal fuse is rated at 4A/250 V.

The relay's self-test element automatically assesses the health of the power module. Primary and secondary tests to ensure device integrity assess hardware functionality and remove power to the power module in the event of a critical fault. If the tests detect a hardware issue or critical fault, the system can indicate to nearby users via LEDs located on the faceplate of all UR devices. Panel LEDs directly related to the power supply include continuous on, on/off cycling, and off.

Frequently Asked Questions About the UR-RHH
What are the unique features of the UR-RHH Universal Electrical Power Supply Module when used with the UR Series Multilin Universal Relay Systems?
The Multilin Universal Relay Systems accept UR-RHH power supplies. The range is 125 to 250 V at 35 W and 100 to 240 VAC at 35 VA. The Multilin UR-RHH features a matte black body to enhance aesthetics and protect the underlying circuit board.
What is unique about the GE Multilin UR Series UR-RHH Second Generation Universal Relay System Power Module compared to the UR-SH power module?
Both the UR-RH power module and the UR-SH power module feature high voltage. The UR-RH power specified in the previous question was 35 W. The output power of the UR-SH has been increased to 45 W. The UR-RH power supply has 27 electrolytic capacitors, while the UR-SH has only one. The isolation voltage level of the UR-RH power module is also unique compared to the UR-SH (2000 V AC and 2300 V AC, respectively). Even with the increased output power, the UR-SH generates the same amount of heat as the UR-RH.
