Frequently Asked Questions about UR-6DH

What is a digital I/O used for in a GE Multilin UR Series Universal Relay such as the Multiline GE Digital I/O Module UR-6DH with the order option 6D?

A GE Multilin UR-6DH Digital I/O Input Output UR Series Universal Relay Module is a specific type of a digital I/O module that may be found within a UR Series universal relay. The unique universal relays have divergent applications.

Some, like the Multilin L60 line phase comparison system, provide protection to lines and cables with different voltage characteristics. Others, such as the B30 bus differential system, provide feeders with impendence biased bus differential protection.

Regardless of the specific type of universal relay and the specific end application, most if not all universal relays contain a digital I/O module in order to provide a universal relay with variable contact inputs and contact outputs.

Different digital I/O modules have model numbers that specify which order option characterizes the module and therefore specifies the specific types of contact outputs and inputs that the module can provide the universal relay and the broader system application.

If the order code includes a Form-A card then that digital I/O relay will have a very low activation speed, which may be beneficial to the end-user. If the digital card has outputs that are mechanical latching then the system may not need a mechanical switch or a lockout relay.
