Overview
The Allen-Bradley 1769-IF16C Series A is a CompactLogix 16-point high-density analog current input module from the Bulletin 1769 Compact I/O family. It is a 16-channel high-density analog current input module that converts and digitally stores analog data for retrieval by controllers such as the CompactLogix or MicroLogix 1500 controllers. The 1769-IF16C has sixteen (16) 0-20 mA / 4-20 mA single ended input channels and occupies only a single slot of the system. This unit ships new in original packaging, making it a reliable drop-in replacement for failed or expanding analog input racks.
Key Features
- Full-scale analog ranges of 0…21 mA and 3.2…21 mA are accepted by this module.
- Internal Sigma-Delta ADC with 15-bit resolution for bipolar configuration and 16-bit resolution for unipolar configuration.
- No field calibration required, with a software-configurable input filter available for each channel to remove irregularities from fast-changing analog signals.
- Parallel sampling updates the entire module (all 16 channels, if enabled) in an amount of time equal to only 8 channel update times.
- DIN rail or panel mounting, open-style enclosure with status LED indicators.
Technical Specifications
Verified specifications for the Allen-Bradley 1769-IF16C Series A based on Rockwell publication 1769-TD006 and the 1769-UM018 user manual.
Typical Applications
The 1769-IF16C is well-suited to process monitoring and machine control applications that require many 4–20 mA loop signals in a small footprint. The 1769-IF16C links field instruments like controllers and transmitters so they can receive feedback from comparable devices like panel meters, data loggers, modulating valves, variable frequency drives (VFDs), and other similar ones, and can also receive conditioned output signals from signal splitters or isolators. Common uses include tank level, flow, pressure and temperature transmitter monitoring on packaging, water/wastewater, and OEM machinery.
Compatibility & Replacements
The Allen-Bradley Compact 1769-IF16C I/O module is compatible with Programmable Automation Controllers (PAC) like CompactLogix and Programmable Logic Controllers (PLC) like the MicroLogix 1500. The 1769-IF16C is configured with RSLogix 500 (when used with MicroLogix 1500), RSLogix 5000 for CompactLogix controllers at version 20.11 or lower, and Studio 5000 for controllers at version 21.00 or higher. Replacement accessories include the 1769-RTBN18 removable terminal block, 1769-RL2 door label, and 1769-RD replacement door. The 1769-IF16V is the companion high-density analog voltage input module for voltage signal applications.
