Below is a typical RTD.
Current Inputs
To connect current (milliamp) inputs, install resistors that convert the
milliamp input to a voltage. Watlow Anafaze offers resistors for 0-20
mA and 0-10 mA current inputs.
Voltage Inputs
•
Connect the + side of the voltage input to the In+ terminal.
•
Connect the - side of the input to the In- terminal for the 4 and 8CLS,
or analog common for the 16CLS. The 0voltage 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, see the Input Scaling sec-
tion.)
The figures below show typical voltage input.
