It's built from plastic with a protective collar and mounts to the floor of the enclosure — not a DIN rail, so plan for that when laying out the panel. The IP20 rating means it's for inside a cabinet, not out on the wet floor. The Safety-Related rating of 2 tells you this module is designed for safety circuits up to SIL 2 or PL d, depending on the system architecture. Those two inputs are meant for dual-channel e-stop or guard monitoring — one channel per input, cross-monitored by the AS-i safety monitor upstream. Dimensions are 71 mm tall, 17.6 mm wide, and 50.1 mm deep. Substance prohibition date is 05/28/2009. No UL or CSA listing is on record for this order code.","metaTitle":"Siemens 3SF5500-0DA AS-i F-slave, 2 safe inputs, IP20","metaDescription":"Siemens 3SF5500-0DA AS-i F-slave with 2 safe inputs for emergency stop enclosures.
