Allen-Bradley 1769-OF4CI
The Allen-Bradley 1769-OF4CI is an analog output module designed for use in Compact I/O systems. Manufactured by Allen-Bradley, a well-known name in industrial automation, this module is ideal for applications that require precise analog control. It is compatible with MicroLogix 1500 and CompactLogix controllers.
Technical Description:
The 1769-OF4CI module offers four differential, individually isolated analog outputs. This ensures reliable performance and reduces the risk of interference between channels. The module supports both unipolar and bipolar output ranges.
It features a digital resolution of 16 bits, offering precise control over output signals. For unipolar outputs ranging from +4 to +20 mA, it provides 15.59 bits of resolution at 0.323 µA/bit. For bipolar outputs ranging from 0 to 20 mA, it delivers 15.91 bits of resolution at 0.323 µA/bit. The conversion rate of the module is 110 milliseconds, ensuring timely response in dynamic environments.
The module’s power supply distance rating is 8, which determines the maximum distance the power can travel without significant loss. It uses a 4-point communication cable, facilitating reliable data transfer. The solid wire size supported by the module ranges from 22 to 14 AWG, while the stranded wire size ranges from 22 to 16 AWG.
The module’s non-linearity is ± 0.05 % of the full scale, ensuring accurate output over the entire range. The 1769-OF4CI module’s shipping weight is 2 pounds, and its dimensions are 8 x 8 x 5 inches, making it compact and easy to install.
Attachments Specifications:
This analog output module does not require calibration, as guaranteed by its hardware design. The series supported are A and B, catering to different application requirements. The full-scale analog ranges include 0 to 20 mA and 4 to 20 mA. Additionally, the module supports field calibration, although it is generally not required due to its reliable design.
The power supply options for the module include 1769-PA2, 1769-PB2, 1769-PA4, and 1769-PB4. The recommended cable for the module is Belden 8761 (shielded), which provides enhanced signal integrity and reduced interference. The module can be mounted on a DIN rail or a panel, offering installation flexibility.
Standard Safety Precautions:
When installing and using the Allen-Bradley 1769-OF4CI module, standard safety precautions should be followed. Ensure the power is turned off before installation to prevent electrical shock. Use appropriate tools and follow the manufacturer’s guidelines for installation and maintenance.
Regularly check the module for any signs of wear or damage and replace it if necessary. Proper grounding and shielding should be implemented to minimize the risk of electrical interference. Ensure that all wiring is done according to the specified wire sizes to prevent overheating and potential hazards.
