Product Description:

The Allen-Bradley 1771-IFF is a "Fast" Analog Input Module designed for PLC-5 programmable logic controller systems. It's configurable for either 8 differential inputs or 16 single-ended inputs, providing flexibility for various analog signal types. The "Fast" designation indicates a relatively high conversion speed for analog signals, making it suitable for applications with rapidly changing analog values. It uses block transfer programming for communication with the PLC-5 processor.

At DD Parts Solution, we may offer both new (if available as surplus) and used/refurbished 1771-IFF modules, depending on availability. Given the age of this product line, used or refurbished units are more common.
