Board, Interface, PWM to 0-10vdc
Item Number: 702108
Manufacturer Part No: dcnc/vfd/opto
This board provides an opto-isolated interface between digital pwm signals and industrial controllers that require an analog input signal. The interface output voltage can be offset using a std resistor or potentiometer for lower than 10VDC input requirements. The unit also offers two opto-isolated channels that provide a contact closure to ground output for stop-start function , or direction control of motor controllers.
- Variable speed DC motor controls
- Variable output AC Drives
- Variable Frequency Drives ( VFD/Inverters)
- Variable output vibratory feeders
- Variable light dimming applications
- Variable temperature controllers
- Other analog input devices
Plug compatible with the DeskCNC controller, other DeskCNC outputs are available with direct to terminal connection ( PWM, CW, and CCW are opto-isolated). This board is also compatible with other systems that use digital PWM signals such as parallel port controllers, ncPOD, Gecko 100, etc.
PWM: Opto isolated pwm, supports 0-50Khz, 0-100% duty cycle, 3-6 VDC pulse Height, and 2-6ma current draw.
CW & CCW: opto isolated from board supply, 3-6 VDC input voltage, 2-6 ma current draw. Poistive triggered.
Mist, Flood, Aux1,2,3 pass through terminal connections from DeskCNC or other source. Isolated from board supply, but not opto-isolated.
0-10vdc linear response to positive period of the PWM signal. Source current 30 ma. Minimum stable load 500 ohm.
CW & CCW - Contact closure to ground. Supports 100vdc 500 ma contact signal. Can be wired to external relay for motor direction control or to VFD CW & CCW inputs.
Power supply: 12vdc regulated or 15-30 vdc unregulated. Up to 125 ma regulated 12vdc available when powered with 15-30 vdc regulated power supply.
Includes ribbon cable and wiring layout, and instructions for wiring to Leeson Speedmaster Controller, and to Automation Direct GS-Series VFD.
