SERIES DESCRIPTION
The RTI-1280 Series products are analog and digital input/output
cards that are compatible with the CMOS STD bus. Designed with
high-speed, low-power CMOS technology, these products provide
low-power, high noise immunity, and extended temperature ranges
operation. They are cost effective and provide a convenient means of
interfacing your CMOS STD bus microcomputer to the real (i.e.
analog and digital) world.
The series consists of an analog input card (RTI-1280), an analog I/O
card (RTI-1281), an analog output card (RTI-1282) and a digital I/O
card (RTI-1287): each of which interfaces to the CMOS STD bus as
either memory mapped or I/O port addressed peripherals through user-
selectable jumpers.
APPLICATIONS
This family of CMOS STD BUS I/O cards solves the problem of
interfacing real-world signals to the
C bus. Using new high-speed
analog and digital CMOS technology, these cards offer low power,
high noise immunity and extended operating temperature ranges.
Described in this technical document are analog and digital interface
cards designed for use in harsh environments, remote sites, and
battery-backed applications. Applications for these products include:
Well Site Supervision
Pipeline Monitoring
Meterological Data Acquisition
Process Control
Medical Electronics
Battery-Powered Instrumentation
SCADA Systems
Energy Management
