Samkoon F series Expansion Module – F 4AI

F-4AI 4-Channel Analog Input Expansion Module

Samkoon F-4AI analog input module A high-precision analog sensor interface designed specifically for the internal BD slot of Samkoon FAs series PLCs and Integrated PLC+HMI All-in-One units.

The F-4AI is a “BD-style” expansion board that provides a seamless way to integrate up to four analog sensors—such as pressure transducers, temperature transmitters, or flow meters—directly into your controller. Because it installs internally, it requires no extra space on the DIN rail, making it perfect for compact control cabinets.
