LCD Screen Name, Description or Function, User Action, Example
Relay Output Setup Start Screen: The output numbers and the output type (relay or analog) are
determined by the module types and configuration of your control system's module assembly and are
automatically assigned when you connect power to the module assembly. (See Setting Up the Control
System in the UI on page 8.)
Note: You must set up the control system input sensors before you can set up the outputs.
1. In the Relay Output Setup Start screen, press
The screen example shows a Relay Output Setup Start screen for Output 1.
Sensor Selection Screen: The sensor you select here determines the output's setup parameters and
values, including condition type, unit of measurement, minimum control band, default setup values, and
setup value ranges for several of the remaining output setup screens. If a sensor is not selected, the
remaining output setup screens do not appear. If a sensor is already selected for this output, the Sensor
Selection screen does not appear here and the Relay ON Selection (ON or dON) screen appears instead.

2. Press
• For standard control action, select Sn-1, Sn-2, or Sn-3.
• For standard control action with High Input-Signal Selection, select HI-2 or HI-3.
• For differential control action, select Sn-d.
• For binary input control of Relay Outputs, select bIn.
Then, press
screen or the Relay dON Selection.
The top screen example shows the initial Sensor Selection screen for Relay Output 1 before a sensor is
selected. The remaining screen examples show some of the sensors that may be available for selection.
For the Output Relay example, Sn-2 is selected as the Sensor for Output 1 as shown in the second
screen.
System 450™ Series Control Module with Ethernet Communications Installation Instructions
You must select a sensor in this Sensor Selection screen and the selected sensor must be already
set up in the System 450 UI. (See Setting Up System 450 Sensors.)
On System 450 control modules with network communications, the functional sensors Sn-d and
HI-2 are available, if Sn-1 and Sn-2 are the same Sensor Type. If Sn-1, Sn-2, and Sn-3 are the
same Sensor Type, the functional sensor HI-3 is also available.
or to select the sensor that this output references:
to save your sensor selection and go to the Standard Relay ON Selection
to go to the output's Sensor Selection screen.
