LPT-CNC-A parallel port interface board is a high-performance interface board designed with high-speed optocoupler (EL817). It uses new pulse shaping technology to isolate computer parallel port and peripherals, effectively protecting computer equipment, so it is very suitable for direct use. As an industrial application, computer control peripherals are excellent interface boards for solving the anti-interference function of on-site switching signal input and digital control signal output.
Characteristics:
1>.Provide 12-channel OC (collector open mode) output, output limit frequency up to 100kHz, five-way optical isolation common ground signal input.
2>.DC +5V power supply, no power supply at the output.
3>.All output signals of the parallel port of the computer are shaped by Schmitt trigger to improve the anti-interference of digital signal transmission.
4>.Can be used with parallel control software as an industrial control application.
5>.support KCAM4, EMC2 / linuxcnc parallel port CNC control software, support up to 6 axes.
6>.can be used with all pulse and direction signal stepping, servo drive, control lathe, milling machine for CNC operation.
7>.The input end can be externally connected with mechanical switch, slot type optocoupler, proximity switch, tool setter, etc.
8>.The interface board P1~P17 port signal corresponds to the computer parallel port signal 1~17 pin one by one, and the parallel port 18~25 pin is the power ground.
