Overview
Features
Major features of PIO-SSR Series boards are as follows:
●
Each group of 24 digital I/O lines terminates in an onboard, 50-pin
header whose pin assignments are compatible with industry-standard
PB-24 and PB-24SM solid-state-relay baseboards.
●
Three board versions are available to drive one, two, or five PB-24
baseboards from a single expansion slot of your computer.
●
Each group of 24 digital I/O channels emulates Mode 0 of an Intel
8255, allowing most of the current application software for data
acquisition to work seamlessly with PIO-SSR Series boards.
●
All boards power up with all lines configured as inputs and pulled
high.
●
All boards provide high-current-drive capability.
●
All boards provides flexible interrupt capability.
●
An onboard 10k
Ω
pull-up resistor connected between each channel
and the +5V gives CMOS compatibility for TTL signals.
●
The software that accompanies each board is compatible with
Windows 3.x and Windows 95.
●
All PIO-SSR Series boards are
⅔
size.
Applications
Typical applications of PIO-SSR Series boards are as follows:
●
Machine control
●
Process monitoring and control
●
Control of solenoids, pumps, motors, and others
●
Contact-closure monitoring
