Product Description

The Siemens 6ES5246-4UB21 is a SIMATIC S5 I/O Module designed for integration with S5 PLC systems, functioning as a digital module. It features 16 digital inputs and 16 digital outputs for direct interfacing with sensors and actuators. The module operates at 24V DC with a voltage tolerance range of 20.4–28.8V DC and is compatible with ambient temperatures from 0°C to 60°C. Designed for rugged industrial environments, it supports seamless expansion via direct connection to additional S5 I/O modules through its proprietary backplane interface. Ideal for manufacturing automation, process control, and machinery applications, this module offers high reliability and robust performance. However, its legacy design limits compatibility with modern communication protocols. It lacks built-in battery support, screen displays, or sensor detection capabilities, focusing purely on digital signal handling. Its compact design ensures space-efficient installation in control cabinets.
