The RTI-1226 Analog Input Card provides the same analog functions
as the RTI-1225, but does not include the two channels of 8-bit analog
output. An ideal choice when only analog inputs are required, this card
can be configured for 0 to + 10V, 5V and 10V input ranges.
Reliable analog connections are made using 3M's "Scotchflex" socket
and header connectors which enable a flat ribbon cable to be combined
with gas tight and corrosion resistant connectors. An optional screw
termination panel is also offered for simple and convenient field wire
connections.
The RTI-1225 series cards come complete with their own dc/dc
converters, allowing the cards to operate directly from the
microcomputer's + 5V supply. Configured as a block of contiguous
memory locations (memory mapped interface), these products simplify
the task of interfacing STD Bus microcomputers to the real world.

SERIES DESCRIPTION
The RTI-1225 series products handle analog inputs and outputs for
STD Bus microcomputer systems. These subsystems provide a cost
effective solution to interfacing with the analog world by minimizing
the hardware development time and providing low function cost.
The RTI-1225 combines both analog input and output functions
on a
single card, thus reducing components count. This design
provides data acquisition of analog signals from 8 differential or
16 single-ended, jumper-selectable voltage inputs and 2
independent voltage outputs. Also included is a differential
amplifier, a sample and hold circuit and a 10-bit A/D converter
(AD571). Throughputs of 25,000 channels per second are
achievable. The analog output section consists of two 8-bit D/A
converters. Each channel has a user selectable output range of 0
to + 10V,
5V and
10V.
