Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 6ES7221-1BF22-0XA0 is a SIMATIC S7-200 digital input expansion module by Siemens. It provides eight discrete digital inputs (sink/source) intended for connection to the S7-22X CPU family. The module installs on the S7-200 backplane and allows extended digital input capacity for small-scale industrial control systems such as conveyor control, machine status detection, or discrete I/O expansion in distributed automation. 6ES7221-1BF22-0XA0 is typically mounted in control cabinets alongside CPU and I/O modules.
Best Suited For
- S7-200 CPU 22x systems requiring additional digital inputs
- Discrete sensor input expansion in conveyor or material handling systems
- Remote machine-status monitoring where eight extra DI channels are needed
- Compact control panels where modular I/O expansion via backplane is prioritized
