The 6ES7223-1BF22-0XA0 is a Siemens SIMATIC S7-200 Digital I/O Expansion Module EM 223, designed to extend the I/O capacity of the S7-200 controller with a balanced mix of inputs and outputs. This module offers 4 digital inputs (24V DC, sink/source) and 4 digital outputs (24V DC, 0.75A per channel), making it ideal for applications requiring moderate I/O density, such as packaging machinery, conveyor systems, and small-scale automation cells. Its compact design allows direct mounting on a standard DIN rail, and the module communicates via the S7-200 backplane bus for fast data exchange. The inputs feature high noise immunity and short-circuit protection, while the outputs include overcurrent and thermal shutdown safeguards. Operating temperature range: -20°C to +60°C, with IP20 protection rating. The module supports both sinking and sourcing input configurations, and outputs are protected against inductive load kickback. For enhanced reliability, each channel is optically isolated from the backplane. This unit is fully tested and certified to meet CE, UL, and CSA standards, ensuring compliance for global deployment.
