• Input LoopTracker® LED
• Relay Status LEDs
• High Capacity Relay Contacts

Applications:

• Valve Position Controller
• Linear Actuator Controller
• Damper Controller

The API 3200 G controls the position of a valve or linear actuator by comparing a DC input (control signal) to that of a position feedback potentiometer or slidewire. An SPDT relay provides bi-directional (open-close) signals to drive a motor to open or close a valve.

When the valve position, as indicated by the feedback potentiometer, becomes equal to the position as represented by the control input, the relay will go to the neutral position and the motor will halt. A top-accessible multi-turn deadband control allows precise positioning of the motor without hunting or oscillation.

The API 3200 G have heavy-duty relay contacts allow the modules to directly control high capacity loads without a secondary device.

Auto/Manual Switch

A top-accessible Auto/Manual switch allows either closed-loop automatic control of valve position or manual positioning via the Open/Close push buttons. The manual mode is useful for troubleshooting, calibration, system testing or as a manual bypass.

LoopTracker and Relay Status LEDs

API exclusive features include a LoopTracker LED that varies in intensity with changes in the input signal. Monitoring this LED can provide a quick visual picture of your process at all times and save time during initial startup and/or troubleshooting. A red/green bi-color LED visually indicates control relay status. The LED indicates green for opening, red for closing and off for neutral position.
