The 1756-IF8 is an I/O module with analog input and it has 8 channels. It is manufactured by Allen-Bradley. It converts analog input to digital signals and change these digital values to analog signals for the outputs. These signals are then used for control purposes by the controllers. The available input resolutions are: +/- 10.25 Volts with a 320 µ Volts/count, 0 to 10.25 Volts with a 160 µ Volts/count, 0 to 5.125 Volts with a 80 µ Volts/count, and 0 to 20.5 milliamps with a 0.32 µ Amperes/count. It has 8 single-ended inputs, 4 differential inputs, and 2 high-speed differential inputs with a 36-pin removable terminal block.

The 1756-IF8 comes mounted in a ControlLogix chassis. It comes with an exclusive Input/ Output diagnostic when it detects a failure. It supports three wiring methods. Single-ended wiring compares one side of the input signal to the ground signal and it is used to generate data for the controller. Differential wiring is used when separate signal pairs are not available. It is widely used in places with improved noise immunity. High-speed differential methods will provide fast data updates. The 1756-IF8 has enhanced accuracy, robustness, and it can perform the same task multiple times over different temperature ranges. It has time-stamping capabilities and it also features electronic keying to reduce errors. It has onboard data alarming which alerts for different events. The Real Time Sampling (RTS) of the channel can be obtained. It has a programmable limit switch and it can function as a smart connection between I/O modules. It does not need on-site calibration.

The 1756-IF8 module is an Allen-Bradley I/O module with analog inputs. This analog module takes in analog signals and converts them into digital values for input. For output, the digital values are again converted into analog signals. This 8-channel module is powered with a voltage rating of 24 Volts DC. The input current range of the analog input module ranges between 0 and 10 milliamps, 0 and 5 milliamps, and 0 and 20 milliamps. It has a voltage resolution of 0 to 10.25 Volts with 160 µV/count and 0 to 5.125 Volts with 80 µV/count, and 0 to 20.5 milliamps of current resolution with 0.32 µV/count. The 1756-IF8 module draws 150 milliamps of current at 5.1 Volts and 40 milliamps of current at 24 Volts. The total backplane power of the analog input module is 1.73 Watts. 

 

The 1756-IF8 module consumes a total of 1.73 Watts of power with normal working conditions. The analog input module dissipates 1.73 Watts of power in voltage operation  and 2.33 Watts of power with current operation. Its thermal dissipation is 5.88 BTU per hour. The 1756-IF8 module has a normal mode noise rejection of less than 80 dB and a common mode noise rejection of less than 100 dB. The analog input module supports the integer mode with a 32-bit floating point data format. It uses the Sigma-Delta conversion method. From input to backplane, a basic insulation of 250 Volts is present. The 1756-IF8 module has a slot width of 1 for installation. The operating temperature range should be set between 0 and 60 degrees Celsius and it can be stored at a temperature between -40 and 85 degrees Celsius. It has an open enclosure and should be used inside the chassis only.

The 1756-IF8 module is an Allen-Bradley I/O module with analog inputs. It comes with 8 channels.
