Product Description

The Siemens 6ES7221-1BF32-0XB0 is a SIMATIC S7-200 Digital Output module designed for reliable 24VDC PLC control systems. This compact module features 8 digital outputs, each capable of switching up to 0.75A, with a total load current of 4A. It operates within a 20.4–28.8VDC voltage range and supports direct connection to expansion modules via the S7-200 backplane. Designed for industrial automation applications like manufacturing and process control, it functions optimally in temperatures from 0°C to 55°C. The module lacks built-in communication ports but integrates seamlessly with RS-485-based S7-200 systems. Key advantages include high noise immunity, plug-and-play installation, and rugged construction, though it requires external isolation for sensitive loads. No integrated battery or display is included. Its compact form factor (71.2mm x 80mm x 62mm) ensures space-efficient cabinet integration.
