ISO-730 Isolated Digital I/O Board

Functional Description
The ISO-730 has 32 optically isolated digital I/O and 32 TTL logic I/O channel. Each of the 16 isolated digital input channel accept voltage from 5V to 24Vdc and has a resistance of 1.2K onm. Every eight input channels use one external common ground. For example, channel 0-7 use EI.COM1 and channel 8-15 use EI-COM2. Each of the 16 isolated digital output channels equipped a darlington transistor. Every eight output channels use the common emitters. The power supplyof the output port should use the external power. The channels 0-7 use EO-COM1 and channel 8-15 use EO-COM2. This interface board is easy installed in any PC/AT/XT. The board interface to field logic signeds, eliminating ground loop problems and isolating the host computer from damaging voltages.
The ISO-730 has one 37-pin D-sub connector and four 20-pin header. It is fully compatible to PCL-730.
