Voltage and Current Control Loops Lab

Controller measurement

Reads voltage to calculate current using Ohm's Law

Actuator feedback

Utilizes voltage or current control loops for feedback

Actuator Feedback

Utilization of voltage or current loop

Measurement Range

Range of humidity sensor readings

Relative Humidity

Percentage based on current readings

Voltage loop

Analog value expressed with voltage in a specified range

Current loop

Analog value expressed with current in a specified range

Voltage ranges

Common ranges: 2-10 VDC, 0-10 VDC

Current ranges

Common ranges: 4-20 mA, 0-20 mA

Current loop advantage

Constant current, avoids voltage drop

Resistor placement

Placed between A and C terminal for Universal Input

Actuator power

Can be powered by AC or DC based on requirements

Actuator rotation

Defines rotation range, DA, RA, and control methods of actuator

Actuator configuration

Set up for specific configurations by changing jumpers

Power wiring

Wiring the actuator using 24 VAC

Control wiring

Connects actuator to controller for input and feedback

Actuator Position

a certain % the actuator can open
