SLC 500 Programmable Controllers and I/O Modules
Analog I/O
Modules
Small programmable controllers
continue to be placed in process
control applications demanding high
densities, faster, more accurate
measurement, and the flexibility to
interface to a variety of temperature,
pressure, and flow transducers.
The SLC 500 family offers multiple
choices that broaden its control
capabilities to serve these and other
demanding applications.
Features
• User-selectable inputs allow you configure each input channel for a
voltage or current signal from the sensor.
• High-resolution outputs that provide for precision control of analog outputs.
• Input filtering on modules provides high immunity to electrical noise or
a fast input response for high-speed applications.
• Backplane isolation that isolates input signals from the backplane.
• Removable terminal blocks that allow you replace a module quickly
without removing the wiring.
• High-density modules that provide more efficient use of chassis space
and lower cost per point.
• Diagnostic feedback that allows machine uptime to be increased and
troubleshooting time reduced, with the help of diagnostic status bits for
open-circuit and out-of-range detection. Channel status indicators and a
module status indicator are also provided.
• Software configurable channels can be individually configured
with the ladder program and can be re-configured without interrupting
CPU operation. An easy-to-use bit configuration table allows the user
to choose the input type, data format, filter frequency, and status data
best suited to the application.
