c) APPLICATION EXAMPLES
The examples introduced in the earlier Direct inputs and outputs section (part of the Product Setup section) are continued
below to illustrate usage of the direct inputs and outputs.
EXAMPLE 1: EXTENDING INPUT/OUTPUT CAPABILITIES OF A T60 RELAY
Consider an application that requires additional quantities of digital inputs or output contacts or lines of programmable logic
that exceed the capabilities of a single UR-series chassis. The problem is solved by adding an extra UR-series IED, such
as the C30, to satisfy the additional inputs/outputs and programmable logic requirements. The two IEDs are connected via
single-channel digital communication cards as shown below.

Assume contact input 1 from UR IED 2 is to be used by UR IED 1. The following settings should be applied (Direct Input 5
and bit number 12 are used, as an example):
UR IED 1:
