Description

GE Multilin URRHH

1. Flexible Voltage Range Selection: URRHH offers two different voltage ranges for users to choose flexibly. The low range (LO) is 24 to 48V nominal (DC only), suitable for equipment or scenarios with strict requirements for DC power supply and relatively low voltage levels; the high range (HI) is 125 to 250V nominal (both DC and AC). This range is compatible with both AC and DC power sources, greatly expanding its application possibilities under different power supply conditions. It can be applied in both conventional industrial facilities mainly powered by AC and special equipment systems partially relying on DC power.
2. Redundant Power Supply Configuration Option: The module provides a redundant power supply option, allowing users to configure flexibly according to the system's different reliability requirements. The redundant power supply design is particularly critical in industrial production processes with extremely high requirements for power supply continuity, such as chemical production and power generation where operation cannot be easily interrupted. When the main power supply fails, the redundant power supply can switch seamlessly and continue to supply power to the relay and related equipment, ensuring uninterrupted system operation, avoiding production downtime, equipment damage, or even safety accidents caused by power supply failures, and effectively improving the stability and reliability of the entire system.
3. Comprehensive Health Monitoring and Protection: The URRHH power module has a built-in perfect health monitoring mechanism, which can automatically evaluate its own operating status with the help of the relay's self-test components. Through comprehensive primary and secondary tests, it can not only accurately determine whether the hardware functions are normal but also quickly take measures to disable the power module in case of critical failures, preventing the failure from expanding and protecting the connected relay and other equipment. Once the test detects a hardware problem or critical failure, the system will immediately send a clear indication to the operator through the LED indicators located on the panel of all UR units. The panel LEDs directly related to the power supply display the current working status of the power module in different states such as continuous lighting, flashing (on/off cycle), and extinguishing, facilitating operators to detect problems in a timely manner, conduct troubleshooting and handling, and ensure the continuous and stable operation of the system.
4. Efficient and Stable Power Supply: As a power module, its core function is to provide stable power to the equipment. URRHH can stably supply the required power to relays and dry contact input connections, ensuring that the equipment will not have malfunctions, performance degradation, or other issues due to power fluctuations or instability during normal operation. Meanwhile, the internal 4A/250V fuse rating design can quickly cut off the circuit in case of abnormal situations such as excessive current, playing an effective overcurrent protection role, preventing damage to the module itself and connected equipment due to current overload, and further enhancing the safety and reliability of power supply.
