1769-IF16C Compact I/O module

The Allen-Bradley 1769-IF16C is a Compact I/O module that is compatible for use with MicroLogix

1500 Programmable Logic Controller (PLC) and CompactLogix Programmable Automation Controllers

(PAC). The 1769-IF16C features Sixteen (16) single-ended input channels that are designed to

interface field instruments that provides 0-20 mA or 4-20 mA analog Current signal towards the module’s input channels.

The 1769-IF16C can be used for interfacing of field instruments such as Transmitters, controllers;

Accept feedback signals of Variable Frequency Drives (VFD), modulating valves, panel meters, data

loggers and similar devices. It may also be used to received conditioned output signals of signal isolators or splitters.

The 1769-IF16C has an internal Signa-Delta Analog-to-Digital (ADC) converter. This converter

translates the received analog signal into digital data with resolution of 16 bits when configured as

unipolar and 15 bits when configured as bipolar. This module accepts full-scale analog input signal ranges of 0-21 mA and 3.2-21 mA.

1769-IF16C

The 1769-IF16C does not require calibration. By configuring an input filter, noises may be

eliminated and insignificant changes are neglected by the module.

If used with CompactLogix version 20.

The 1769-IF16C has a BUS draw current of 190mA at 5 Volts DC and 70mA at 24 Volts DC and

dissipates 4.0W of heat. It has an input overall accuracy of 0.5% at 25 degrees Celsius (77

degrees Fahrenheit) for 16 Hertz, 50 Hertz, and 60 Hertz selectable filters, and an input drift

accuracy of ±0.0045% per degrees Celsius. It has ±0.03% non-linearity, ±0.03% at 16 Hertz

filter repeatability, and 1.25% at 16 Hertz filter module error margin.
