Wiring for AI with a 4 to 20 mA Sensor.

 

 

 

NOTE: 

If the voltage/current switch is set to 

current and a 4 to 20 mA sensor is 

connected to an AI, then special 

wiring requirements must be followed. 

 

 

 

 

 

NOTE: 

When wiring any actuator that uses a 0 to 

10V control signal and ties AC neutral to DC 

common, an additional wire must connect 

the actuator AC neutral to the DC common 

of the PTEC/TEC AO being used to control 

the actuator.
