The A1210-B is a solid-state relay designed for industrial AC switching applications with a 90-280 VAC control voltage input and 24-140 VAC output operating range. It features SCR output technology rated for 10A maximum load current with zero voltage turn-on capability, direct bond copper substrate, and a thermal resistance of 1.03°C/W for efficient heat dissipation. The relay is UL/CSA/TUV approved and CE compliant to EN60950-1, with an epoxy-free design and improved SEMS screw termination. It is well-suited for heavy industrial loads requiring reliable AC switching with low on-state voltage drop of 1.15 Vrms and excellent EMC compliance to Level 3.
