Product Details

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.

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