DC Motor Amplifier + Plasma Interface
Driver for 24V DC motors with tacho feedback to control the torch lifting, with electrical connections for interfacing plasma generatorors.
Installation logical diagram:
Integrating DC motor driver with plasma interface circuit makes the electrical connections easier and reduces installation cost.
Features
- 24VDC Motors amplifier with tacho feedback
- Adjustable maximum power up to 250W
- +/-10V Input for motor speed command
- +24VDC Input for drive enable and motor brake
- "Cut Start" digital input from controlling logic and output to plasma with galvanic isolation
- "Arc Transfer" filtered digital input from plasma and output towards controlling logic
- "V Arc" filtered analog input with protection fuse and output towards controlling logic
- Electrical connections with anti-vibration spring contacts
- Open-frame panel mount
- 24VAC Supply
Automatic Plasma Arc-Voltage Stand-Off Unit
This unit controls automatically the cutting clearance between plasma torch and plate, by means of the voltage applied to the ends of cutting arc.
Installation logical diagram:
The device is controlled by means of digital I/O (up, down, auto) making the interfacing very simple and easy to operate with hard-wired logic or CNC not equipped with programmable logic.
Features
- Input-adjustable cutting height with memory
- Can be easily interfaced with any CNC/PLC or hard-wired logic
- 24VDC motor amplifier with or without tacho feedback
- Adjustable maximum power up to 250W
- AMP connector for I/O and motor interface
- Separate AMP connector for plasma interface
- Analog output proportional to cutting height (for external display)
- 24V AC/DC supply
- Dimensions: 185x120x55mm
