GM824 A_D

This appears to be a “bought-in” card, which was originally sold as IO824 and later sold under the GM824 part number.

There are 8 analogue input channels (J1-J8) which are 0-5V with 8-bit resolution. All inputs have over-voltage protection. Signal conversion time is approx 30us, including a sample-and-hold phase.

The system has full interrupt control and user-configurable I/O addresses.

Has anyone got any more info on this board?
