Product Description

The Siemens 6ES7221-3AD30 is a compact S7-1200 Digital Input PLC Module designed for industrial automation. It features 8 high-speed 24V DC sink/source input channels, supporting direct integration with sensors and switches. The module operates within a 20.4–28.8V DC voltage range and functions reliably in temperatures from -20°C to +60°C. It connects seamlessly to the S7-1200 CPU via an integrated backplane, supporting up to 8 expansion modules for scalable system configurations. Widely used in manufacturing, logistics, and process control, this module offers robust noise immunity and configurable diagnostic alarms. Limitations include no onboard communication ports, requiring a separate CPU for network connectivity. Input signal detection ranges from 15V DC (minimum ON) to 5V DC (maximum OFF), ensuring precise signal interpretation.
