The 4030 ISA digital I/O interface is designed around two 8255 chips, each providing 24 I/O lines. The board has a Dip-switch for flexible I/O addressing, IRQ jumpers for interrupts and two sets of connectors for each port. A standard 50-pin solid state relay I/O module connector and a 40-pin connector with power and IRQ signals are provided. The 50-pin connects (through an optional cable) to industry-standard PB-8, -16 or -24 solid state relay I/O modules. The 40-pin connector, terminated in an optional DB-37 cable, matches the pin-out of Generic PIO-12 boards.

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 4×8, 2×16 or 1×32 matrix switch.

The 3094 ISA digital I/O interface provides 16 optically isolated inputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop current that can be generated in industrial environments.

The inputs on the 3094 are rated for 3-13V. For 10-30V inputs, order the 3094H.
