The 3098 ISA digital I/O interface relay output adapter provides four banks of eight switched Reed relays. The card's DB-37 connector brings out the A-side of all relays while the optional B-side connector brings out the B-side and commons of all relays to a second DB-37 connector. This allows access to both sides of all 32 switches. The REL-32 can easily be configured as 32 independent relays, or as a 4x8, 2x16 or 1x32 matrix switch.

Sealevel's SeaIO Classic software drivers and utilities make installation and operation easy using Microsoft Windows operating systems.
