1-2 Overview
General Description
The analog input module converts and digitally stores analog data for
retrieval by controllers, such as the SLC-500 programmable controller.
The module supports connections from any combination of up to four
voltage or current analog sensors. The four high-impedance input
channels can be wired as single-ended inputs.
The output module provides two single-ended analog output
channels, either voltage or current, depending on the module
selected.
Table 1.1 lists the CompactBlock LDX module types and
corresponding operating ranges:
Each analog base module supports up to two CompactBlock LDX
discrete expansion modules.
