Figure 2.18 Linear Voltage Signal Connections
Current Input Connections
This input type requires scaling resistors. Special input re-
sistors installed at Watlow Anafaze for analog current sig-
nals are such that the controller sees a -10 to 60 mV signal
across its inputs for the loop.
Figure 2.19 Linear Current Signal Connections
NOTE!
When mixing current inputs with low-voltage
inputs (thermocouples or voltage inputs <1V)
to a CLS216, connect the current signal to the
IN+ and Ref Com terminals. When no low-
voltage sensors are used, connect current in-
puts to the IN+ and Com terminals on TB1.
For all inputs to a CLS204 or CLS208, con-
nect the sensors to the IN+ and Com termi-
nals.
