EVB-5000 Evaluation Board

The EVB-5000 Evaluation Board is a development tool designed to allow fast and inexpensive evaluation of Airtrol's SDU-5000 series Stepper Motor Driven Regulators. When used in conjunction with the calibration data included with every SDU-5000, the EVB-5000 can be used to confirm repeatability, step rate, linearity, etc., of the regulator. The EVB-5000 features an on board clock and counter, and can be configured to run the SDU-5000 from 8 to 8184 steps. The EVB-5000 is also capable of accepting external control inputs, to assist in developing software and feedback loops. This feature also allows the EVB-5000 to be used in simple stand alone control applications where sophisticated electronics are not available.
