Product Description

General Electric Multilin’s UR-7DH is an Inter-Relay Communications Module that offers a single channel. The provided channel is a 1300 nm, single-mode LASER channel. 

The relay, in conjunction with the module, is able to detect the deterioration or failure of communications channels and activate an alarm in order to alert users to the active situation. Integrated channel monitoring provides users with data pertaining to channel health, which can be reviewed easily using Multilin’s EnerVista UR software program. The relay is capable of reactively responding to shifting channel variables and maximize the potential for channel health. 

The UR-7DH module is a good choice for users seeking to replace old modules of a similar nature or for users seeking to upgrade their Universal Relay which did not come with interrelay communication capabilities. Prospective buyers can reference the order code tables for their respective Universal Relay; any order code segment with an “XX” indicates that the given relay does NOT come with that module installed, making purchasing it a potential necessity if those capabilities are required.

Frequently Asked Questions about UR-7DH

Reviews For UR-7DH

Internal Review
(4.0)

While the UR-7DH is an excellent choice for interrelay communication, it does only offer one channel; prospective buyers should ensure two channels are not needed and can reference the replacement module order codes (found in most UR user manuals) to gain a better understanding of what each module variation offers. -AX Control Tech Team
