The Allen-Bradley 1769-IF16C is a compact I/O module compatible with the MicroLogix 1500 Programmable Logic Controller (PLC) and the CompactLogix Programmable Automation Controller (PAC). The 1769-IF16C features sixteen (16) single-ended input channels designed to connect field instrumentation to provide a 0-20 mA or 4-20 mA analog current signal to the module's input channels.

The 1769-IF16C can be used as an interface for field instruments, such as transmitters, controllers; Accepts feedback signals from variable frequency drives (VFDS), regulator valves, panel meters, data loggers and similar devices. It can also be used to receive conditioning output signals from signal isolators or splitters.

The 1769-IF16C has an internal Signa-Delta analog-to-digital (ADC) converter. The converter converts the received analog signal into digital data with a resolution of 16 bits when configured as unipolar and 15 bits when configured as bipolar. The module accepts a full scale analog input signal range of 0-21 mA and 3.2-21 mA.

The 1769-IF16C does not require calibration. By configuring the input filter, noise can be eliminated and the module can ignore insignificant changes.

If used with CompactLogix version 20.


The 1769-IF16C has a bus current consumption of 190mA at 5 V DC and 70mA at 24 V DC, and can dissipate 4.0W. For 16 Hz, 50 Hz, and 60 Hz selectable filters, it has an overall input accuracy of 0.5% at 25 degrees Celsius (77 degrees Fahrenheit) and an input drift accuracy of ±0.0045% per degree Celsius. Its nonlinearity is ±0.03%, ±0.03% at 16 Hz filter repeatability, and 1.25% within the 16 Hz filter module error range.

The 1769-IF16C has a maximum overload of ±28 mA at 7.0 V DC of the input terminal and is built with IEC enhanced insulation with an isolation voltage of 30 V DC, tested at 710 V DC/500 V AC, and held for 1 minute between input group and BUS isolation. It has an operating impact rating of 30G for 11 milliseconds in the panel mount mount mode and 20G for 11 milliseconds on the DIN rail. The 1769-IF16C has an operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and a transport temperature range of about -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit).
