The controller houses a data acquisition unit, a microprocessor(s) for the brake(s), power supplies, and other system components. In addition, controllers may come pre-wired for transducers and alternative inputs to be captured by the MBS software.
The footprint of the controller is approximately 17.25” wide x 17.0” deep and 7” tall. It weights around 28 lbs.
In the back of the dynamometer's controller are the input jacks to couple the signal cables from the dynamometer structure, a USB cable to couple to the computer and a DB9 style connector. One of the inputs in the DB9 is allocated for the “Ready Signal.” This signal allows the operator to start and stop a test remotely for time-sensitive tests. The operator may configure and “arm” the dynamometer. When a signal ranging from 3.3 VDC to 10 VDC is sent to the controller, the system starts capturing data. When the test is done, or the signal falls below 3 volts, the test stops.
