ABB 07AC91 Analog I/O Module | Distributed Automation PLC Module

Product Overview

The ABB 07AC91 Analog I/O Module is a high-performance distributed automation module designed for ABB AC31 PLC systems. Built for demanding industrial control applications, it offers flexible analog signal processing with up to 16 configurable analog channels and supports voltage, current, and thermocouple inputs.

Unlike conventional analog modules with fixed channel assignments, the 07AC91 provides two selectable operating modes. Users can configure it as 8 analog inputs plus 8 analog outputs with 12-bit resolution, or as 16 configurable analog channels operating in pairs with 8-bit resolution. This flexibility makes it an excellent solution for process automation, machine control, water treatment, energy management, and manufacturing systems requiring adaptable I/O configurations.
