AB 1769-OF4CI Compact I/O 4-Ch Analog Current Isolated

Technical Specifications for 1769-OF4CI

About  1769-OF4CI

The Allen-Bradley Compact I/O module with part number 1769-OF4CI is analog output module with embedded Four (4) differential, individually isolated channels. This module has an output current signal of 0-20mA and 4-20 mA with full analog current range of 0-21 mA and 3.2-21 mA respectively. This module belongs to the 1769 Compact I/O system and designed in compatibility with MicroLogix 1500 and CompactLogix controller. This module may also be installed in a remote I/O chassis using DeviceNet communication adapter with part number 1769-ADN or Ethernet Communication adapter with part number 1769-AENTR.
Primarily, analog output modules are used to drive Final Control Elements (FCE) or actuators to implement multiple control points. Available data formats are Raw / Proportional data, Engineering unit, Scaled for PID and Percent full range. Configurable channels parameters include output range selection, module inhibition, module description and slot assignment. The module generates a unique data table for each instance of installation where the channel addresses, module mode bits, module state and other runtime parameters.

This module is a low maintenance module. It has auto-calibration that is performed by the module every time the module is power cycled. Additionally, self-test is performed every power cycle. Once the module enters self-test, the module is unresponsive. It will automatically enter active operation, new values is actively compared to the high and low clamp settings to prevent the output from exceeding the defined limits.
