1-2 Overview
General Description of the
Module’s Hardware and
Diagnostic Features The analog input channels convert and digitally store analog data for
retrieval by controllers, such as the MicroLogix™ 1500 and
CompactLogix, and from network adapters like the 1769-ADN (Series
B) DeviceNet Adapter. 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 either single-ended or
differential inputs.
The output channels provide two single-ended analog outputs, each
individually configurable for voltage or current.
The module provides the following input/output types/ranges:
The modules provide the data as raw/proportional data. If scaling to
engineering units is required, it must be done in your control
program.
Hardware Features
The module has a removable terminal block. The module’s four input
channels can be wired as either single-ended or differential inputs.
The module’s two output channels are single-ended only. Module
configuration is done via proper wiring of the I/O and the controller’s
programming software. In addition, some controllers support
configuration via the user program. In either case, the module
configuration is stored in the memory of the controller. Refer to your
controller’s user manual for more information.
