The Schneider Electric VW3A16903 is a +/-10V REF ADAPT. MODULE, a reference adapter module designed to interface analog speed reference signals in drive systems. Its function is to condition and adapt a +/-10V analog signal for use with compatible variable speed drives, typically in applications requiring precise speed or torque control from an external potentiometer, PLC analog output, or process controller.
The module accepts a bipolar +/-10V analog reference for drive speed/torque setpoint inputs.
