PCI board with 24 digital I/O, High output drive and SIP sockets for pull-up/pull-down resistors 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.
The PCI-DIO24H/SIPSCKT is a digital high-density I/O card with SIP sockets for installing pull-up/pull-down resistors. The PCI-DIO24H/SIPSCKT offers 24 bits of digital I/O. 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.
It is based on the 82C55 chip. The use of pull-up and pull-down resistors is important if you need to set a fixed value to avoid the input value being floating.
