The DK1A1B-12V is a compact, single side stable polarized power relay designed for high-capacity switching. It operates with a nominal coil voltage of 12V DC and features a 1 Form A 1 Form B (Au-flashed AgNi type) contact arrangement. The relay has a nominal switching capacity of 8A at 250V AC with a low nominal operating power of 200mW. Key electrical characteristics include a high breakdown voltage of 4,000 Vrms between the contact and coil and a surge breakdown voltage of 10,000V. Its sealed construction makes it suitable for various applications, including switching power supplies, industrial machinery, programmable logic controllers, and home appliances.
