Allen Bradley Bulletin 865

The Allen Bradley Bulletin 865 relays are differential protection relays. They can support nominal current and nominal earth-fault current ratings of up to 5 Amps. Some Bulletin 865 relays operate with just DC voltage, and some models operate with AC and DC voltage. These differential protection relays are available with IP30 or IP54-rated enclosures, and some models have conformal coats for additional protection. The hardware options available with different Bulletin 865 relays include serial interfaces, plastic and glass serial fiber interfaces, Profibus interfaces, and different types of Ethernet interfaces. These relays can be controlled by built-in pushbuttons, connected PCs, or remote control devices.
