It carries a Safety-Related rating of 2, meaning it supports a safety function up to SIL 2 / PL d per the AS-i Safety at Work protocol, suitable for guarding a hazard zone where an e-stop is the primary protective device. Floor mounting is the specified fastening method, which per the datasheet means it sits on the floor of the enclosure rather than on a DIN rail, so plan for a dedicated mounting footprint. Height is 71 mm, width 17.6 mm, depth 50.1 mm. ## Operating range and compliance Ambient temperature during operation spans -25 to +70 °C, which covers most industrial cabinet environments without forced cooling. Substance prohibitance date is 05/28/2009.","metaTitle":"Siemens 3SF5500-0BA AS-i F-slave, 2 Safe Inputs, IP20","metaDescription":"Siemens 3SF5500-0BA AS-i F-slave with 2 safe inputs for emergency stop housing.
