UR6CH Digital I/O module

Ge’s UR-6CH is a digital I/O module that provides the UR relay with the ability to communicate with

auxiliary equipment by providing digital input and output. This particular unit provides 8-Form C digital

output. The Form-C digital output is a single pole double throw (SPDT) contact, indicating that there is a

common point connected to a normally closed contact (NC) and a normally open contact (NO). Type C

can switch between these two outputs and is therefore often referred to as a “switching” contact.

The Universal relay family is designed with scalability in mind, providing a hinged panel that allows access to

module brackets within it for easy installation and upgrading. Although the enhanced and normal models

differ slightly in accessing the module brackets, both devices provide a relatively easy entry point for hardware modifications.

Potential buyers should ensure that the module they purchase fits their power system needs, as other digital

I/O relays in the same family offer different contact forms and functions. The series also offers devices with

rated trip type A contacts, solid state relay contacts or A, C and SSR combinations. Solid state output modules

provide fast tripping, high current break capability, and fast reset time, making them ideal for direct tripping applications.
