Isolated Current-Source type Digital I/O Board for ISA

This product is PC/AT which performs current-source type isolated type digital input and output, and an interface board for the compatible machines. This board can be used being able to mount in the expansion slot or I/O extension unit of the main part of a personal computer, and can be outputted and inputted a maximum of 32 points on this one board. This board is a current sauce type current-source type about a current-sinking type and an output in an input.

	The input (sauce output correspondence) of a maximum of 32 points and the output (sauce type) of a maximum of 32 points can be performed on one board. It can respond to a common independently different external power supply because of the common composition of an eight-point unit.
	Since the PCI bus (personal computer) and the input/output interface are isolated by the photo-coupler, it excels in noise-protection nature.
	Four of 32 input signals can be used as an interruption input.
	Output rating is designed by a maximum of 35VDC and 150mA (however, 1 common per a maximum of 2A) large scale per point.
	It has the digital filter for preventing the incorrect input by the noise or the chattering, an output monitor, STB/ACK data communications, and the bit unit input-and-output function.
