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 to connect field instruments such as transmitters and 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 consumption current of 190mA at 5 V DC and 70mA at 24 V DC, with a heat dissipation of 4.0W. For 16 Hz, 50 Hz, and 60 Hz selectable filters, it has a total input accuracy of 0.5% at 25 degrees Celsius (77 degrees Fahrenheit) and an input drift accuracy of ±0.0045% per degree Celsius. It has a ±0.03% nonlinearity, a ±0.03% repeatability of a 16 Hz filter, and a 1.25% error range of a 16 Hz filter module.
The 1769-IF16C had a maximum overload of ±28 mA at 7.0 V DC of the input terminal and was tested for 1 minute at 710 V DC/500 V AC between the input group and BUS isolation with IEC-enhanced insulation and an isolation voltage of 30 V DC. It has an operating impact rating of 30G for 11 milliseconds in panel mount mount mode and 20G for 11 milliseconds on DIN rail. The 1769-IF16C has a functional temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and a transport temperature range of around -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). It weighs about 281 grams (0.62 lb) and has a shipping dimension of 118 x 87 x 35 mm (4.65 x 3.43 x 1.38 in).
