The Allen-Bradley compact I/O module with Part number 1769-OF4CI is an analog output module with embedded four (4) independently isolated channels. The module has 0-20mA and 4-20 mA output current signals with full analog current ranges of 0-21 mA and 3.2-21 mA, respectively. The module belongs to the 1769 Compact I/O system and is designed to be compatible with MicroLogix 1500 and CompactLogix controllers. This module can also be installed in a remote I/O chassis using a DeviceNet communication adapter with part number 1769-ADN or an Ethernet communication adapter with part number 1769-AENTR.

The analog output module is primarily used to drive the final control element (FCE) or actuator to achieve multiple control points. Available data formats include raw/proportional data, engineering units, PID scaling, and full range percentages. Configurable channel parameters include output range selection, module suppression, module description, and slot assignment. This module generates a unique data table for each installation instance that contains the channel address, module mode bits, module status, and other runtime parameters.

This module is a low maintenance module. It has an automatic calibration function, which is performed by the module every time the module is powered back on. In addition, a self-test is performed for each power cycle. After the module enters the self-check state, the module does not respond. It will automatically enter the active operation, and the new value is actively compared to the high and low clamp Settings to prevent the output from exceeding the defined limit.

The 1769-OF4CI is a four (4) channel analog current isolation output module in the CompactLogix family manufactured by Allen-Bradley. The 1769-OF4CI features 16-bit resolution and supports the Belton 8761 shielded compact analog module cable. The 1769-OF4CI has 20 µV per piece from 330 to 0mA and a bus current of 5 V DC 165 mA. The unit also has 2.0 watts of heat dissipation. It has a conversion rate of 110 ms and a finite voltage of greater than 2.9 ms per current ratio. The module has a resistive load of 0 to 500 ohms and a rated output inductance load of 0.1 mH. The 1769-OF4CI carries electrostatic discharge that may damage integrated circuits or semiconductors. Therefore, when touching the device, touch the grounded object to release the electrostatic potential. Avoid touching bus connectors or connector pins, and use an anti-static workstation (if available). When not in use, 1769-OF4CI should be stored in a static shield box.
1769-OF4CI has an accuracy of +/-0.35% and an accuracy drift relative to temperature of +/-0.0058% FS per degree Celsius. 1769-OF4CI has +/-0.05% nonlinearity and +/-0.005% repeatability. It has no specified field calibration, a module error boundary of about +/-0.55%, and a rated output impedance of less than 1 MOhm. The device also has the function of open circuit and short circuit protection, and has the function of output overvoltage protection. It is able to maintain its full operating capacity at a maximum short-circuit current of about 21 mA. The 1769-OF4CI compact current output module measures 118 x 35 x 87 mm (4.65 x 1.38 x 3.43 inches) and weighs 270 g (0.60 lb).
