The Siemens 6ES7136 is an ET 200SP Series safety module operating at 24 V, designed for fail-safe signal handling within a distributed I/O rack. It sits in the PLC I/O & Expansion Modules category, meaning it integrates into a Siemens ET 200SP station alongside standard I/O slices and communicates over the backplane bus.
