Frequently Asked Questions about UR-7IH
Does the UR-7IH COMMS Module GE Multilin UR Series Universal Relay have a LED component for use in communication capabilities?
The UR-7IH COMMS Module is used in certain universal relay systems such as the B30 bus differential system and the L90, which is a line differential relay. In either case, the UR-7IH COMMS Module provides the universal relay with communication features. The UR-7IH COMMS Module GE specifically has characteristics that are chosen with the 7I order code. There are multiple different order code options. In the B30 bus differential system catalog, the user has the option to choose between the 2B, 2I, 2J, 7A, 7B, 7C, 7H, 7I, 7J, 7S, 7W, and 77 order options. Each order option allows the COMMS module to have variable features. The 7I order code (found in the UR-7IH COMMS module) is characterized as having a 1300 nm multimode LED with two channels.
How many channels does a COMMS module typically have in the UR series of universal Multilin relays?
The COMMS modules may come with different channels depending on the specific order code at hand. The UR-7IH COMMS Module GE for example has two channels. Generally the COMMS modules will range between either 1 or 2 channels that may be LED, ELED, or have a LASER component in some cases.
