Overview.
This board provides 5 optoisolated sinking inputs for +24VDC
signals and 12 optoisolated sourcing outputs for 24VDC
signals.
Features
• Fully
optoisolated The card isolates connections to protect your
computer from short-circuit. An opto-isolator is an integrated
circuit that transmits the signal through an encapsulated LED and
phototransistor. When the signal is on, the LED lights up, the
phototransistor captures it and relays the signal. In that way,
your computer’s electronics are completely isolated from the cnc
circuitry. The signals are transmitted through light and not
through physical connections. In this way, a power surge has no way
of reaching your computer. That is the reason why this card has two
power connections. One power connection is power powering the
circuit that interacts with the PC, the other connection is for
powering the circuit that interacts with your cnc system. Extra
precautions have been taken when designing this circuit, by taking
into consideration the extremely high voltages that stepper drivers
can achieve and lack of experience that some users could have in
wiring circuits of this kind.
• Buffered outputs. All inputs and
outputs are buffered through the use of high speed and high power
buffers. Each pins deliver 100 milliamps.
• IEEE 1284 Standard compatible.
Includes the circuitry recommended by the IEEE 1284 Level 1
standards for bidirectional parallel communications between
personal computers and peripherals
• Darlington
Outputs.
• External Enable Pin (EN). The board
has a pin that allows you enable/disable all the outputs at once.
The board requires +5vdc in the EN pin. If it is not present, it
will send all the outputs to ground immediately. You can use this
enable and disable your system manually, or you can install an
external Safety Charge Pump or other external
device.
• Status LEDs on all inputs and output
connections. No more guessing. You can SEE all your
signals. Save valuable time and brainpower for
cncing.
•
Works directly with popular CNC hardware and
software. Such as Geckodrive, DeskCNC or Rutex, and
parallel port control software, such as mach2, Linux EMC, TurboCNC,
CNCPlayer, CNCZeus and others. (Not all tested)
