Phoenix IB IL AO Series – Analog Output Modules

The Phoenix IB IL AO Series (INTERBUS Inline Analog Output Modules) provides precise analog output control for automation and process applications. These modules are part of the Inline I/O system, known for its compact design, flexible configuration, and easy integration with a wide range of PLC and control systems.

Each module converts digital control signals into analog voltage or current outputs, enabling accurate control of actuators such as valves, drives, and indicators. The IB IL AO series is optimized for space-saving installation, stable performance, and cost efficiency — ideal for modular and distributed automation architectures.

1. General Overview

The IB IL AO (Analog Output) modules are designed to output standard process control signals such as 0–10 V, ±10 V, 0–20 mA, or 4–20 mA.
They interface directly with programmable logic controllers (PLCs) via the Phoenix INTERBUS or Inline communication system, offering plug-and-play configuration and fieldbus compatibility.

Key design goals of the IB IL AO series include:

• High-accuracy analog output generation

• Compact 12 mm or 24 mm width housing

• Ease of wiring with pluggable terminals

• Integrated diagnostics and status LEDs

• Compatibility with ECO, PAC, BP, and SF product variants
