The A1210 is a panel-mount solid-state relay designed for industrial AC switching applications with 90-280 VAC control voltage input and 24-140 VAC output capability. It features SCR output technology optimized for heavy industrial loads, with a rated load current of 10A and zero voltage turn-on switching as standard. The relay incorporates a direct bond copper substrate, aluminum baseplate, and UL 94 V-0 housing material, operating reliably across an ambient temperature range of -40°C to +80°C. Key performance characteristics include a maximum on-state voltage drop of 1.15 Vrms at rated current, transient overvoltage rating of 600 Vpk, and dielectric strength of 4000 Vrms between input/output/base. The A1210 is UL/CSA/TUV approved and CE compliant to EN60950-1, making it suitable for industrial automation, motor control, heating systems, and other AC load switching applications requiring reliable solid-state switching with minimal maintenance.
