Phoenix IB IL AI 8/IS-PAC Analog Module

Phoenix Contact IB IL AI 8/IS-PAC Analog Input Module (Inline System I/O Module)

 

The Phoenix Contact IB IL AI 8/IS-PAC is an Inline analog input module used in industrial PLC and automation systems. It belongs to the Phoenix CONTACT Inline I/O system and is designed to collect analog current signals from field devices and send them to a PLC/controller.

Product Information

• Brand: Phoenix Contact (Germany)

• Type: Analog input I/O module
• Channels: 8 analog input channels
• Signal type: 0–20 mA, 4–20 mA, ±20 mA (current inputs)
• Function: Signal acquisition (field instruments → PLC system)
• Installation: DIN rail Inline terminal system

What it actually is

This module is used to read industrial sensor signals, such as:

• Pressure transmitters
• Flow meters
• Temperature transmitters
• Level sensors
• Industrial 4–20 mA devices

It converts these analog signals into digital data for PLC control systems.

It does NOT operate independently.

System Role (Simple)

Field sensors (4–20 mA signals)
→ IB IL AI 8 module (this unit)
→ PLC / controller system
→ control logic execution
→ outputs to machines

So it acts like a “signal acquisition interface between sensors and PLC.”
