The PMDX-407 is a basic spindle speed control interface with isolated analog output for use with PMDX SmartBOB-USB boards.

• Regular version is used as a daughter board on the PMDX-410, PMDX-412, PMDX-414, PMDX-416, PMDX-422, and PMDX-424.
• Logic power and PWM signal are provided via the daughter board connector.
• Uses reference voltage from VFD or an external power supply as a source of isolated analog power
• Sets spindle speed using PWM from CNC control software
• Single signal interface uses PWM signal for both speed, and On/Off (absence of pulses stops motor) 
• Works with analog interfaces that use 5 volts, 10 volts, or up to 15 volts
• Provides isolated solid state switch to turn spindle on and off via VFD control inputs. a small relay, or some contactors such as the PMDX-ContactorMD20-120
• Can work with the relay on a PMDX-422, PMDX-416,or PMDX-424 to provide direction control.
• Fully isolated interface can be used with non-isolating VFD's and motor drivers
• Provides speed calibration pot for setting maximum speed
• LED's for PWM signal and RUN command.
• Manual run/stop, speed, and direction control are possible using an external pot, relays, and/or switches
• Optional stand alone version is available for freestanding operation with other breakout boards or for use with the PMDX-340.
• Optional stand alone version works with any system that can supply a 100 Hz to 1 KHz PWM signal. 
• Optional stand alone version has screw terminals for PWM input and 5 to 15 VDC power. It does not have the ribbon header connections.
