SES INP2409 Model 2409 Industrial Analog Input Module

The INP2409 (2409) is an industrial analog input module designed for DCS and process control systems. It collects 4‑20mA or 0‑10V analog signals from field transmitters, converts them into digital data and transmits the measured values to the main controller for closed‑loop process regulation.

This rack‑mounted module supports multi‑channel signal acquisition, overvoltage protection and channel fault diagnosis. Original production has been discontinued. It is widely supplied as aftermarket spare parts for chemical, power and water treatment automation system maintenance and reconstruction.
