Input Wiring Recommendations
Use multicolored stranded shielded cable for analog inputs.
Watlow Anafaze recommends that you use 20 AWG wire
(0.5 mm 2 ). If the sensor manufacturer requires it, you can
also use 24 or 22 AWG wiring (0.2 mm 2 ). Most inputs use a
shielded twisted pair; some require a three-wire input.
The controller accepts the following inputs without any
special scaling resistors:
• J, K, T, S, R, B and E thermocouples.
• Process inputs with ranges between -10 and +60 mV.
To avoid thermocouple open alarms on unused inputs, ei-
ther set the Input type parameter to skip or jumper the in-
put.
Thermocouple Connections
Connect the positive lead of the thermocouple to the IN+
terminal for one of the loops, and connect the negative lead
to the corresponding IN- terminal.
