1769-IF16C AB 16-Channel Current Input Module
Technical Specifications
The 1769-IF16C offers a current input range of 0-21 mA full scale. Normal operating ranges include 0-20 mA and 4-20 mA. Additionally, it supports a full range of 3.2-21 mA.
Channel diagnostics: Over-range/under-range bit reporting, process alarms
Backplane current: 1.4 A at 24V DC
Power consumption: 33.6 W
Power dissipation: 7.5 W
Isolation voltage: 30V DC
Overall accuracy: 0.5% at 25°C (16/50/60 Hz filters)
Drift accuracy: ±0.0045% per °C
Non-linearity: ±0.03%
Repeatability: ±0.03% at 16 Hz filter
Module error margin: 1.25% at 16 Hz filter
Furthermore, the module does not require calibration. You can configure an input filter to remove noise and ignore minor signal changes.
Mechanical & Environmental Parameters
The 1769-IF16C fits into a single slot in a 1769 chassis. It has an open enclosure type and is rated for industrial environments.
Dimensions (H x D x W): 118 mm x 87 mm x 35 mm (with tabs: 138 mm)
Shipping dimensions: 8 x 8 x 5 inches
Weight: 0.62 lbs (281 g)
Operating temperature: 0 to 60°C (32 to 140°F)
Storage temperature: -40 to 85°C (-40 to 185°F)
Operational shock: 30G for 11 ms (panel mount), 20G for 11 ms (DIN rail)
Maximum overload: ±28 mA at 7.0V DC at input terminal
Specifically, the module uses reinforced insulation per IEC standards. Isolation is tested at 710V DC / 500V AC for one minute between input group and bus.
Installation Guidelines
Before installation, confirm that your controller is compatible. The 1769-IF16C works with CompactLogix (version 20 or later) and MicroLogix 1500 systems.
Use a shielded cable such as Belden 8761 for best noise immunity. Mount the module in a 1769 chassis or on a DIN rail. Keep the power supply distance rating of 8 in mind when designing your system.
Finally, always power down the system before inserting or removing the module. This prevents damage to the backplane or the unit itself.

Frequently Asked Questions (FAQ)
1. What controllers work with the 1769-IF16C?
The 1769-IF16C is compatible with CompactLogix PACs (firmware version 20 and up) and the MicroLogix 1500 PLC.
2. Does this module support 0-10V input signals?
No. The 1769-IF16C accepts only 0-20 mA and 4-20 mA current signals. For voltage inputs, consider the 1769-IF16V model.
3. How do I wire the 1769-IF16C?
Use a shielded cable like Belden 8761. Connect each analog input to a single-ended channel. Follow the wiring diagram in the user manual for proper grounding.
4. Can I use this module in a hazardous location?
The 1769-IF16C has an open enclosure rating. It is not certified for hazardous areas unless installed inside an appropriate enclosure.
5. What is the typical failure mode for the 1769-IF16C?
Channel over-range or under-range conditions are the most common issues. However, built-in diagnostics report these faults through bits in the input data table.
