Specification

SEODescription

The Siemens 6ES5252-5BB11 Module, part of the Siemens S5 Digital Input Module series, is a 24VDC 16-channel PLC module designed for industrial automation. It features 16 digital input channels for processing 24VDC signals, enabling direct integration with sensors and switches. Compatible with Siemens S5 PLC systems, it connects via a backplane bus and supports seamless communication within modular setups. Operating within a voltage range of 20.4–28.8VDC and a temperature range of 0–60°C, it suits harsh environments in manufacturing, process control, and machinery. Key advantages include high reliability, compact design, and robust noise immunity. However, it lacks analog input support and requires compatible S5 backplane hardware, limiting flexibility for modern upgrades. Ideal for legacy systems needing digital signal handling.
