» Functional Description
The ISO-813 is a bus-isolated 12-bit A/D board for PC/AT compatible computers.
Its isolation range is increased to 3000 V that extend the application field to real industry application.
It is backward compatible to 813 families. When compared with PCL-813 or ACL-8113, the ISO-813 adds x16 Programmable Gain Control range.
On-board FPGA increase the stability of this board. It is the most cost effective isolated A/D board in the world.
If the user need high sampling rate, differential input and FIFOs-on-board isolated A/D card, please refer to our ISO-AD32.
