The 1756-IF16 belongs to the Controllogix analog input/output module manufactured by Allen-Bradley. It is part of the mounting chassis class. The 1756-IF16 is equipped with 16 analog input channels to enhance the flexibility of the device. The 1756-IF16  is the best analog input-output system, and the best in its class to accurately convert incoming analog signals into digital signals that are compatible with other equipment. The converted digital signals can be used to control AC motor induction, electromagnetic devices, and so on. The 1756-IF16 is fitted with a producer or consumer network system that generates essential information when required as well as giving additional functions for efficient performance.

Some of the notable features offered by the 1756-IF16 include the ability to remove modules and take out terminal blocks while the equipment is in the power mode, rolling timestamps of data which is 15-bit data specifically designed for module timestamps with millisecond resolution, and multiple data formats offered in the IEEE 32 bit floating point or 16 bit integer data formats. The 1756-IF16 can detect over-range or under-range situations and scale the device to engineering units with alarm. This analog input module has 16-bit resolution and the analog output resolution stands at a 13 to 16-bit resolution. This variety in the module’s resolution allow detection of data changes. The communication system of the 1756-IF16 delivers a producer/consumer communication system which is a complex and intricate data exchange system between modules where each module has the capability to produce data without having to be polled initially. The 1756-IF16 is pre-installed with factory calibration settings. However, the device can be re-calibrated according to consumer preference on the basis of a channel-by-channel or a module-wide basis. This feature enables the 1756-IF16 to be extremely accurate in its performance.

The Allen-Bradley 1756-IF16 module is a ControlLogix voltage/current analog I/O module. A total of 16 single-ended inputs, 8 differential inputs, or 4 differential (high-speed) inputs are available on the module. The configurable input ranges are +/-10 Volts, 0 to 10 Volts, 0 to 50 Volts, and 0 to 20 milliamps. The input resolution is 320 microvolts per count for a +/-10.25 Volts range, 160 microvolts per count for a 0 to 10.25 Volts range, 80 microvolts per count for a 0 to 5.125 Volts range, and 0.32 microamps per count for a 0 to 20.5 milliamps range. At 5 Volts DC, the 1756-IF16 module draws 150 milliamps from the chassis backplane, and it draws 65 milliamps at 24 Volts DC. The total power consumption rating of the module is 2.33 Watts.

For voltage inputs, the power dissipation of the 1756-IF16 module is 2.3 Watts, and for current inputs, the power dissipation for the module is 3.9 Watts. For voltage inputs, the thermal dissipation of the 1756-IF16 module is 7.84 BTU per hour, and for current inputs, the thermal dissipation for the module is 13.3 BTU per hour. The input impedance for the voltage inputs is greater than 10 megaohms, and for the current inputs, it is 249 ohms. For voltage inputs, the overvoltage protection rating on the 1756-IF16 module is 30 Volts DC, and for current inputs, the overvoltage protection rating is 8 Volts DC. The slot width of the module is 1. The data format supported by the 1756-IF16 module is the integer mode (left justified, twos complement). The module conversion method is sigma-delta conversion. The enclosure of the 1756-IF16 module is open.
The Allen-Bradley 1756-IF16 module is an I/O module with 16 input channels. It can be used for both voltage and current inputs.
