1.0 OVERVIEW
This card has been designed to probe by detecting the contact 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 12 or 24VDC.
•Signals and power connections 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

User’s Manual Page 2
WARNING: 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
While 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.
Open Collector - Sinking
TTL - Sourcing

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 to have the circuit and
relays powered the capacitor. Once sensing is complete, the enable should be disabled so the
capacitor can be charged again to be ready for next sensing sequence.
