UR-8FH | GE Universal Relay Module

GE UR 8FH Multilin Universal Relay ModuleThe UR-8FH is the CT/VT described as having the standard 4CT/4VT. It does not have the sensitive ground feature, which allows the universal relay to be protected on grounded systems that are classified as high-impedance. The modules that have this feature are the UR-8G, UR-8J, UR-8M, and UR-8R order codes. These mentions are of the newer CT/VT generation. There are two older CT/VT modules (UR-8B and UR-8D) which also have the sensitive ground fault protection capability. The standard models with the 4CT/4VT feature for example does have the typical up to 24 analog current transformer and voltage transformer capacity as described of all the CT/VT modules incorporated into the various universal relays. In addition to the CT/VT modules, the universal relays also have a transducer I/O module. This provides the UR with either DCmA cards or RTDs to monitor flow, wind speed, temperature, vibration, or pressure. Analog outputs can also be used to connect the UR to an external PLC or other user interface devices. The universal relays also have a digital I/O module that contains up to 96 contact inputs and up to 64 contact outputs.
