TABLE OF CONTENTS

 

1.0         OVERVIEW

This card has been designed to detect contact by sensing the interaction between the torch and the plate.

 

2.0         FEATURES

 

  • Optoisolated input works with signals between 5 to 24VDC or Open collector.
  • Status LEDs.
  • Electromechanical Relays with NO and NC positions.
  • Can be powered with 12V or 24V DC.
  • Signals and power connections are fully isolated from the probing input.
  • It should be compatible with any plasma system.  Instructions and configuration files provided for Mach3, Mach4, and UCCNC.
  • Din Rail Support.

3.0         DESCRIPTION

 

 

 



⚠️

Check the polarity and voltage of the external power source and connect the 12VDC to 24VDC and GND. Overvoltage or reverse-polarity power applied to these terminals can cause damage to the board and/or the power source.

 

4.0         TERMINAL BOARD

4.1      POWER

Regulated +12VDC to +24VDC at @80mA is required to power this board.

                                                           

 

4.2      INPUT SIGNAL

This board supports TTL or Open Collector 5 to 24VDC signals.

💡

Note: The below wiring diagrams are an example, any input can be used for the connections.

4.3      INTERNAL CIRCUIT                  

 

 

 

💡

Note: there is no direct line between the power or signals of the probe and the rest of the circuits. That the probing circuit is being powered by capacitors and the signals handled by relays.


4.4      INPUT SIGNAL TOUCH

The enable signal needs to be active while sensing is enabled.  This is to have the circuit and relays powered by the capacitor.  Once sensing is complete, the enable should be disabled so the capacitor can be charged again to be ready for the next sensing sequence. 

                               

 

 

 

5.0         PTS-1 Times

5.1      Time to fully charge the capacitors.

 

5.2      Time that remains active.

 

6.0         INDICATOR LED

6.1      POWER

Switch on the power supply, and the red LED will light. (Power LED)

 

6.2      ENABLE

The LED on indicates that it is enabled

 

6.3      TOUCH

When touched, the red LED will turn on.
