CNC4PC

Overview

This card has been designed to provide a flexible interface and functions to your computer projects, by using the parallel port control software. This board comes as a response to many customers that have been asking for a faster way to connect devices and reduce the possibility of wiring errors.

Features

· Built-in Safety Charge Pump.

It has a built-in safety charge pump that can be enabled or disabled. It also comes with an external enabling if you would also need an additional safety control device.

· Easy installation of an On/Off switch. You can control the card externally.

An On/Off or an additional Safety Charge Pump can easily be installed to enable or disable the card. CNC could be dangerous machines and, remember, safety comes first. Having the power supplied externally gives you the ability to turn your system on or off. This card is provided with an extra pin (EN) that allows you to control the card externally by enabling or disabling outputs externally. The card must have +5vdc supplied in the EN pin to enable outputs. You can hardwire the connection if you are not going to use this safety feature. That way can choose which safety feature to implement, or a combination of both, or no safety feature at all.

· Built-in Optoisolated Variable Speed Control.

It has an analog 0-10VDC output that will convert a step signal into an analog signal that can be used to command a commercial VFD.

· Built-in 8 amp AC Solid State Relay.

It is very useful to use a solid state relay instead of a mechanical relay for starting motors or other devices that might produce arcs at contact. This will increase the life of the motors and relay. This relay is also optoisolated from the rest of the board and has a replaceable fuse.

· Built-in 8 amp Solid State Relay with NO and NC positions.

Mechanical relays are very flexible because they can be used for AC or DC and come with NO and NC (Normally Open and Normally Closed) positions.

· Buffered outputs.

All inputs and outputs are buffered through the use of high speed and high power buffers, with the result that your devices receive all the power they need.

· Output pins 1,2,3,4,5,6,7,8,9,14,16,17.

· Input pins 10,11,12,13,15.

· Status LEDs on all inputs and output connections.

No more guessing. You can SEE all your signals. Save valuable time and brainpower for cncing

· Inputs and output pins with close by ground connections.

Easily connect your pin by using your close by ground connection. No need to be an electronics expert to ground all your stuff.

· All TTL 5VDC signals.

Interface directly with parallel port interface products and other CNC4PC cards. 5VDC (TTL) cards are very common among automation devices.

· Works directly with popular CNC hardware and software.

That goes for Geckdrive, DeskCNC or Rutex and parallel port control software such as mach2, Linux EMC, TurboCNC, CNCPlayer, CNCZeus and other/ (Not all have been tested).

· Screw-On connections for all terminals.

You only have to screw-on the wires to make all your connections. For powering the board you can use the new power supply found under accessories.
