Voltage Inputs
•
Connect the + side of the voltage input to the In+ terminal.
•
Connect the - side of the input to analog common. The voltage input
range is -10 to 60 mV.
•
Scale signals larger than 60 mV with scaling resistors that make full
scale input 60 mV. (For more information about scaling resistors,
request Watlow Anafaze's technical note, Installing Scaling Resis-
tors in the CAS.)
The figure below shows a typical voltage input.
Unused Inputs
Set the input type for unused inputs to "SKIP" to avoid the default T/C
break alarms. (See Input Type in Chapter 4: Setup for information on
setting the input type.)
Back Terminal Block Connections
Wire inputs to the back terminal block as shown here.
