BJORGE STI-AI4-1 Analog Input Module

 

 

Product Overview

The BJORGE STI-AI4-1 is a 4-channel analog input module used in industrial / marine automation systems. It is designed to collect analog signals from field instruments and convert them into digital data for PLC or controller systems.

Typical signals supported include:

• 0–10 V voltage signals
• 0/4–20 mA current signals
• Industrial sensor feedback signals
