The ISO-730 card provide 32 isolated digital I/O channels (16 x DI and 16 x DO) and 32 TTL-level digital I/O channels (16 x DI and 16 x DO). Each of the 16 isolated digital input channel accept voltage from 5 V ~ 24 VDC and has a resistance of 1.2 kOhm. 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 supply of 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 signed, 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. |
