General Electric Multilin’s UR-6EH, a module for upgrading or replacing the current module in the general purpose relay family, is a digital I/O module. This module provides digital inputs and outputs to the relay, enabling it to communicate with devices in a given power system. This particular module provides 4 Form C outputs and 8 contact inputs for the relay. The Type C digital output is SDPT (single-pole double-throw), allowing switching between normally open (NO) and normally closed (NC) contacts.

Wiring instructions related to the digital I/O function can be found in any general purpose relay user manual. These manuals also provide graphics that give a deeper insight into the wiring process, thus simplifying the job for users. The user manual also includes information related to modifying Settings that affect the UR-6EH module and its functions, so it is useful to refer to any general relay manual for a number of reasons.

Users may question which relays in the general purpose series this module is effective for; This digital I/O module is an excellent choice for any relay in the system with relays that can communicate devices in real time.

Frequently Asked Questions about UR-6EH
What is the function of the General Electric Multilin UR-6EH digital I/O module in the UR series?
The Multilin UR-6EH digital I/O input/output module is used to provide contact input or contact output for general purpose relays in the UR series of general purpose relays. These input and output contacts are useful for Multilin universal relays in order to control and monitor equipment within substations or equipment that handles protection functions. Each digital I/O can be distinguished from other Multilin I/O digital models by the type of protection card included in the module. These cards can be classified as Form A, Form C, SSR (solid state relay) or fast Form C.
