Product Description

The Siemens S7-200 Digital Module 6ES7221-1EF22-0XA0 is a SIMATIC Digital Input PLC module providing 8 isolated 24VDC inputs for direct sensor integration. Designed for S7-200 systems, it supports up to 7 expansion modules via flat ribbon connectors, operating at 20.4-28.8VDC with a 4mA typical input current. With a rugged industrial rating (0-55°C operation), it excels in manufacturing, packaging, and machinery control. This 6ES7221 series module features high noise immunity and LED status indicators for real-time monitoring. Key advantages include compact design, easy installation, and compatibility with standard S7-200 CPUs. Limitations include no built-in communication ports, relying on the host CPU for network connectivity. Its screw terminal design ensures secure wiring in vibration-prone environments.
