ABB Distribution Protection Unit R Relay Installations Communications Ports The DPUR has a standard 9-pin RSC interface on the front for serial port communications. Connect a 9-pin RSC cable and 9-pin null modem adaptor from this port to your personal computer to have direct point-to-point.

ABB DPU , DPU R, TPU and TPU R relays have the capability to allow a read only 4X register to be forced from a personal computer through the relay's communication port. SCADA REDI ® allows one port (attached to a computer) to. The types HU, HU-1, HU-4 relays are high speed relays used in the differential protection of transformers. These relays can be applied where the magnetizing inrush current to the transformer is severe. Power Distribution Unit (PDU) kVA power distribution system. Data centers are the essential ingredients that enable individual businesses to have an electronic presence on the Internet. Reliable uninterrupted power is critical to the mission of any organization's data center. The Cyberex PDU offers the most reliable and flexible power.
