The 1771-ASB, manufactured by Allen Bradley, functions as a remote I/O adapter within the PLC 5 series. It is capable of supporting connections to both remote I/O modules and programmable controllers, enhancing the flexibility of system integration. The adapter can be installed in the leftmost slot of the I/O chassis, facilitating straightforward deployment in compatible setups. The 1771-ASB/D remote I/O adapter module serves as an interface betweenI/O modules in a remote I/O chassis and programmable controllers. The adaptermodule can interface to any mix of 8-, 16-, and 32-point I/O modules in an I/Ochassis, plus a wide variety of intelligent or specialized modules and I/Oscanners. The adapter module provides 2-slot, 1-slot, and 1/2-slot I/Oaddressing. This allows it to interface to I/O modules of any density whileusing a minimum number of words in the I/O image table.

The 1771-ASB Allen Bradley Remote I/O Adapter Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
