HDBB2 Breakout Board
HDBB2 Breakout Board – Vico CNC
The HDBB2 is a breakout board used to connect to CNC control
electronics. The HDBB2 breaks out the signals to the stepper
drives, relays, limit switches, homing switches etc.
All the
outputs and inputs are opto-isolated protecting your control
PC and micro controller from external electrical signals from
your CNC machine.
Product Features:
• Centronix-36 connector for standard LPT cable connection
• IDC-26 connector for DSUB-25 ribbon connection
• 4 x Open-drain MOSFET outputs for external relay control – very useful here as any relay up to 45V can be switched. Or switch a 12V relay directly.
• When switching relays and external hardware ensure the power supply to the cad (12VDC) is specified correctly.
• 4 x RJ45 servo or stepper axis connections
• All 5 inputs optically isolated
• 1 analogue output for VFD control
• Built in charge pump safety function
• LEDs on all in and outputs for easy visual debugging
• Extremely versatile card for CNC control
