Digital DC speed controls are preferred by engineers for their accuracy, repeatability, on-board diagnostics, integral digital display, configuration flexibility, and support for both analog signal following and serial communications.



Closed loop microprocessor based motor speed control.
The MD plus is a field-programmable closed loop DC drive system employing an advanced velocity-form PID algorithm for accurate and responsive control. The MD plus system also features a unique, isolated 4-20mA input and output for easy integration with existing Process Control systems. Standard features include: 1/50 to 2.0 HP range, Universal power supply supports 85-265 VAC input, 1/8 or 1/4 DIN panel mount with NEMA 4X faceplate, or NEMA 4 stand-alone enclosure, Front panel field-programming (with lock-out jumper), Target and actual speed can be any engineering unit of measure, Two alarm relay outputs (form C, 5 Amp @ 250 VAC), Large 1/2 in LED display, Master/Follower modes, Displays set point or actual running speed, Adjustable PID settings
