Setpoint Control with PI Function

The 266 Series PI Interface provides set point control for the Hoffman Controls 709 Series of PSC motor controls, the 790 Series of ECM motor controls, and the 865-3AA PSC motor control.

The 266-PI Interface accepts a 2-10 VDC or 4-20 mA signal input and will drive the selected Hoffman control as required to meet desired set point level using a proportional plus integral (PI) control algorithm.
This control is typically utilized with a velocity, pressure, or temperature (thermostat) sensor as input. It then provides a signal to drive the motor control so that the input matches the set point on the control.
