6ES7221-1BF32-0XB0 New Original Siemens S7-1200 Plc Programming Controller module

2. Key Selling Points

1. Compact Digital Input Module: Specifically designed for Siemens S7-1200 PLCs, with a small footprint that mounts directly to the right of the CPU, saving control cabinet space—ideal for compact and space-constrained control systems.
2. 8-Channel 24V DC Digital Inputs: Provides 8 digital input channels with switchable sink/source (PNP/NPN) capability, compatible with various field devices such as pushbuttons, sensors, and limit switches, offering high application flexibility.
3. High Electrical Isolation: Features galvanic isolation between input channels and the internal PLC system, effectively suppressing field noise and enhancing system immunity and operational stability.
4. Plug-and-Play, Easy Integration: As a native expansion module for the S7-1200 system, it requires no additional power supply or software configuration—automatically recognized by the CPU upon power-up for fast installation and commissioning.
5. Industrial-Grade Reliability: Built to meet rigorous industrial standards, with strong electromagnetic compatibility (EMC) and wide operating temperature range, ensuring long-term stable performance in demanding environments.
