An optional battery module extends that to 200 days — useful for seasonal or remote installations where power loss frequency is low. Four high-speed counters (30 kHz each, 32-bit) can handle incremental encoders with two 90° offset pulse trains at up to 20 kHz, enabling direct connection to position feedback without a separate counter module. The RS 485 port supports MPI (up to 187.5 kbit/s) and PPI (9.6/19.2/187.5 kbit/s) protocols for communication with operator panels and other S7-200 CPUs. For new designs, verify that the S7-200 platform still meets your performance and memory requirements; if you are retrofitting an existing S7-200 system, this exact order code replaces the same CPU in service. Quoted to order against a firm RFQ with lead time confirmed at quote.","metaTitle":"Siemens 6ES7212-1AB22-0XB0 S7-200 CPU, 24V DC","metaDescription":"Siemens S7-200 CPU 6ES7212-1AB22-0XB0, currently in active production.
