It measures 45 x 100 x 75 mm (W/H/D), mounts on a DIN rail, and draws 0.07 A from a 19.2... 28.8 V DC supply. ## Key Ratings & Fit Rated MTBF of 273 a indicates long service life for continuous operation. Power dissipation is just 1.6 W, so panel thermal management is minimal. ## Certifications & Compliance Carries UL 508 and CSA C22.2 No. 142 safety listings for North America. ATEX II 3 G Ex nA II T4 and FM Class 1 Div 2 approvals cover hazardous locations. Marine approvals include DNV, NK, LRS, and BV for vessel installations. EMC: emitted interference per EN 61000-6-4 Class A, immunity per EN 61000-6-2. ## Sourcing & Panel Integration Supply connects via the included 3-pole terminal block. No managed-switch configuration required — it operates transparently. Siemens provides industrial security guidance; integrate into a holistic security concept for the installation. Current lifecycle status means this part is specified into active designs.
