1756-IF8I

The Allen Bradley 1756-IF8I is an advanced input module tailored for ControlLogix systems, featuring a total of 8 input channels. It can operate in two distinct modes, specifically voltage and current, granting users the flexibility to handle diverse signal types. The module accepts input voltages in multiple ranges, including -10 to 10 volts, 0 to 10 volts, and 0 to 5 volts, as well as an input current range of up to 20 mA.

Users can configure the inputs in any combination of voltage and current modes to meet specific application requirements. The backplane connection delivers 5.1 volts DC at 200 mA or 24 volts DC at 400 mA, ensuring reliable operation.

Of note is the sourcing functionality, requiring a minimum voltage of 20 volts DC, while it can accept a maximum of 36 volts DC in an open circuit state. The module employs the Sigma-Delta conversion method, which contributes to greater accuracy and resolution of the input signals. This device is designed for installation in a single slot and has an open-style enclosure, offering ease of integration into various control cabinets.

The operational temperature for this input module spans from 0 to 60 degrees Celsius, making it suitable for standard industrial environments where consistent performance and protection are essential. The 1756-IF8I thus serves as a robust solution for capturing both voltage and current signals in a variety of applications.
