PBM is pleased to announce that it is offering a New ControllerCard for AC and DC Impellers, Axial Fans and Blowers.  The controller card accepts a Thermistor(Temperature sensor) input and outputs a PWM speed control signal to the Air Moving device. The higher the Temperature the higher the RPM. 

The card is capable of driving two Air Moving devices at once. The card feeds back to the system  Tach outputs and Alarm outputs from each of the two Air Moving Devices
