GE Multilin UR6EH Digital I/O Module

Overview of Multilin UR6EH

The Multilin UR-6EH Digital I/O Input Output Module serves to provide contact inputs or contact outputs to universal relays in the Universal Relay UR Series. These input and output contacts are useful to a Multilin universal relay in order to control and monitor equipment that are found within a substation or within equipment that handle protective functions. Each digital I/O can be differentiated from other Multilin I/O digital models with the type of protection card that is incorporated in to the module. These cards can be classified as Form-A, Form-C, SSR (solid state relay), or fast Form-C. The General Electric Multilin UR-6EH Digital I/O Input Output Module is characterized with a 6E order code. This alphanumeric designation is found after the “UR-”which stands for universal relay. These different I/O digital options allow the universal relay to be appropriate to each need, no matter how demanding. The 6E order code for the General Electric Multilin UR-6EH Digital I/O Input Output Module shows that the I/O module has four Form-C outputs and 8 digital inputs for use in the UR Series of Mutilin universal relays.

UR BASIC DESIGN

The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output signals. The UR can communicate over a local area network (LAN) with an operator interface, a programming device, or another UR device.

The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as programmable logic gates, timers, and latches for control features.

Input elements accept a variety of analog or digital signals from the field. The UR isolates and converts these signals into logic signals used by the relay.

Output elements convert and isolate the logic signals generated by the relay into digital or analog signals that can be used to control field devices.
