Description

Allen-Bradley 1756-IF8

Description:The 1756-IF8 is an analog module. This module comes with several key safety features. Using these features users can establish connections with actuators and I/O sensors. It comes with a finger-safe cover and one built-in removable terminal block. At +/-10 volts direct current, the resolution rating on this module is 15 bits. For other signal types, the supported resolution is 16 bits. This module needs to be supplied with 1.73 watts of power. It comes with overvoltage protection that can withstand 30 volts direct current and 8 volts direct current.

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.
