1756-IF8IHK

The Allen Bradley 1756-IF8IHK functions as an analog input module designed for use within the ControlLogix framework. This module integrates with various systems, providing accurate signal processing. It boasts a remarkable resolution rating of 24 bits, which allows for detailed measurements. At a temperature of 25°C, its accuracy rating stands at 0.05%, making it suitable for applications that demand precise data. Each of its 8 channels is individually isolated, ensuring reliable operation and reducing cross-channel interference. The module can operate across a voltage range of 0 to 10 V and a current range from 0 to 20 mA.

For signal conversion, the 1756-IF8IHK employs Sigma-Delta techniques that enhance its data processing capabilities and minimize noise. The inherent module error is measured at 0.10%. With a fast scan time of only 1 ms, the device is capable of keeping up with rapid process changes while capturing vital information.

The sourcing voltage for this module is flexible, ranging from 20 VDC to 36 VDC, which contributes to its versatile integration into both new and existing systems. At 24 VDC, the backplane current draw is 150 mA. In terms of power efficiency, it dissipates 4.6 Watts in voltage mode with a thermal dissipation of 15.7 BTU/hr for compatibility in thermal management. Furthermore, the isolation voltage is rated at 250 V, providing additional safety features for system reliability.
