1794-IF4I

Designed for versatility, the Allen Bradley 1794-IF4I input module integrates seamlessly into Flex I/O systems. This unit employs a Sigma-Delta conversion type, promoting accuracy in data collection and user-defined measurements. The device can be configured to accept both voltage and current inputs, catering to a diverse range of applications.

For current inputs, select from options that include 0 to 20 mA, 4 to 20 mA, and -20 to 20 mA ranges. When measuring voltage, choices encompass -10 to 10 volts, 0 to 10 volts, -5 to 5 volts, and 0 to 5 volts. This variety makes the module adaptable to various sensor types and setups, ensuring broad compatibility.

Input resistance properties are significant for application reliability—voltage terminal input resistance exceeds 10 Megaohms, while current terminals present less than 100 Ohms resistance. With respect to overload protection, the 1794-IF4I supports a maximum voltage overload of 30 volts for a single channel and can handle up to 32 mA continuous for current load without damage.

Designed to function in demanding environments, the module operates effectively within an ambient temperature range of -20 to 55 degrees Celsius and can endure storage temperatures dropping to -40 and reaching up to 85 degrees Celsius. In terms of environmental resistance, it maintains integrity within relative humidity levels of 5 to 95% while preventing condensation. Shock resistance measures 30 G, underscoring the unit's ruggedness for various industrial applications.
