Wiring Current Inputs
Current inputs have a range of 4 to 20 mA. Connect the current input according to Figure 8 if you are using a
2-wire, 4-20 mA transducer.
Connect the current input according to Figure 9 if you are using a 3-wire, 4-20 mA transducer.
Connect the current input according to Figure 10 if you are using a transducer powered by its own power.
Wiring Voltage Inputs
Voltage inputs have a range of 0 to 10 VDC. Connect the voltage input according to Figure 11 if you are using a 3-
wire 0 to 10 V transducer.
Output Wiring
Each controller has physical connections for triac outputs and/or universal outputs, depending on the type and
model. The outputs are all software configurable. Table 1 shows the controller outputs.
