About the SIEMENS S5 series 

Main features
Versatility: The S5 series PLCs are not only capable of open-loop control, but also of closed-loop control, positioning, counting, proportionality, valve control and many other functions.
Intelligent I/O modules: These PLCs are equipped with intelligent I/O modules that can autonomously perform special tasks with demanding timing, and are directly connected to the process through input/output channels, thereby reducing the CPU load.
Redundant systems: The S5 series offers redundant systems, which ensure high reliability and availability of the system. For example, the S5-95F and S5-115F are fail-safe PLCs for applications that are dangerous to people, materials or the environment. The S5-115H and S5-155H systems are used in situations where production downtime must be avoided.
Distributed I/O systems
Flexibility: For situations where the distance between the process and the I/O modules is large, the 6ES5 series supports distributed I/O systems. For example, using ET 100U electronic terminals, the I/O modules can be installed up to 3 kilometers away from the process. The ET 200 distributed I/O system allows the use of distributed I/O, microcontrollers and a large number of field devices, the latter of which can reach up to 23 kilometers of programmable controllers.
Network connection: The connected devices are networked via the PROFIBUS-DP high-speed fieldbus, which complies with the EN 50 170 standard.
Specific models
6ES5-90U, 6ES5-95U series: Includes different models of programmable controllers, such as 6ES5090-8MA01 (90U host, 10 inputs, 6 outputs, expandable to 48 points) and 6ES5980-0MB11 (90U backup lithium battery).
6ES5482-4UA11/20: S5 482 digital I/O module, providing 16 or 24 inputs, 24V DC and 8 or 16 outputs, 24V DC; 0.5A.
