It's a current-production node for AS-Interface networks, rated IP20 so it lives inside a control cabinet or junction box — not on the machine frame where washdown hits it. Floor mounting means this module screws to a panel baseplate or backplane — no DIN-rail clip. At 50.1 mm deep, 22.1 mm wide, and 71 mm tall, it tucks into tight spaces alongside terminal blocks or other fixed-mount gear. The metal enclosure handles the vibration and heat dissipation of a crowded enclosure better than plastic would.","metaTitle":"Siemens 3SF5500-0CB AS-i A/B-Slave, 4 Inputs 3 Outputs, IP20","metaDescription":"Siemens 3SF5500-0CB AS-i A/B-slave module with 4 digital inputs and 3 digital outputs.
