Product Overview
Need to capture multiple analog current signals without expanding your panel footprint? The Allen-Bradley 1769-IF16C packs sixteen single-ended input channels into a single-slot Compact I/O module. It accepts 0–20 mA and 4–20 mA signals from transmitters, VFDs, and modulating valves. This high-density design reduces wiring time and rack space compared to using multiple low-channel modules. Built for CompactLogix and MicroLogix 1500 controllers, it delivers reliable performance in oil, gas, and industrial automation applications. Oil AutoTech supplies this module with fast dispatch, worldwide.

Key Parameters That Drive Performance
The 1769-IF16C uses a Sigma-Delta analog-to-digital converter to translate incoming signals into digital data. With 16-bit unipolar resolution, you capture fine process changes. The 0–21 mA full range provides headroom for over-range conditions. Channel diagnostics report over- or under-range conditions via bit reporting and process alarms, helping you detect faults early. The module requires no calibration, saving maintenance time. An input filter eliminates noise and ignores insignificant changes, keeping your data clean.
Where It Fits in Your Operation
In oil and gas, this module interfaces with pressure and flow transmitters. Its 16 channels monitor multiple points on a single skid. For VFD feedback, it accepts analog signals to confirm motor speed. In water treatment, it reads modulating valve positions for precise flow control. The 1769-IF16C also works with panel meters and data loggers when you need to capture conditioned signals. Its single-slot width saves rack space in dense control cabinets.
Compatibility and Integration
The 1769-IF16C works with CompactLogix and MicroLogix 1500 controllers. It fits any 1769 Compact I/O chassis. For wiring, use Belden™ 8761 shielded cable to reduce electrical noise. The module has a power supply distance rating of 8, meaning it can be placed up to eight slots from the power supply. When integrating into a network, you may need an external gateway or connection module. Confirm cable and gateway requirements with your supplier.
Selection and Maintenance Tips
Before ordering, verify your controller model and available slot width. The 1769-IF16C requires a 1769 Compact I/O chassis. Check that your field devices output 0–20 mA or 4–20 mA signals. For maintenance, inspect connections periodically and follow the manufacturer’s safety manual. The module’s no-calibration design reduces downtime.
