About the UR-9HH
General Electric Multilin’s UR-9HH is a CPU module designed for the Universal Relays series, furnishing the relay with computing power by means of logic frameworks, powerful algorithms, and system appropriate latches and gates. The CPU module also works closely with other modules in the relay to assist in organizing their functions and the data they collect. GE Multilin’s UR-9HH also provides the unit with communications functions, such as governing the RS485 port located at the back of the relay.
GE Multilin has produced a wide variety of CPU modules which supply the given Universal Relay unit with different capabilities. For example, some units provide the relay with Ethernet, some units do not provide Ethernet at all, and some units provide Ethernet with additional capabilities, such as Parallel Redundancy Protocol (PRP) and IEEE 1588 protocol.
Most Multilin modules come in a horizontal or vertical form, with the horizontal form taking up more space than the vertical one. This makes the vertical unit ideal for prospective buyers working with a limited amount of space in their power system. Users should ensure they are buying modules appropriate for their relay’s orientation, denoted in the model number by an “H” or a “V”.
