Specifications

PCI board with 24 digital I/O with surge suppression/protection. An 82C55 chip provides the 24 I/O lines on three 8-bit ports (A, B and C), C port can be divided into two 4-bit ports (C-HI and C-LO), DB37 port of 37 pins for direct connection to the 82C55.

The PCI-DIO24-S is a digital I/O card that offers 24 bits of digital I/O. The card is plug-and-play. It includes a surge suppressor circuit that protects the card's I/O against spikes or rises of ± 15 kV (air) or ± 8 kV (contact). It does not have switches, jumpers or potentiometers on the card. Provides 24-bit I/O groups based on 82C55, mode 0. Each group provides an A port and an 8-bit B port as well as an 8-bit C port that can be divided into 2 4-bit C ports: Puerto C-Hi, Puerto C-LO.

Features:

24 digital I/O bits
Protection/Suppression of spikes on the card
Provides direct connections to 82C55
Compatible with a wide variety of relay and SSR modules
Software compatible with CIO-DIO24
Connector compatible with the CIO-DIO24
