The AZ9731-1C-24DC3-R1 is a single-pole, double-throw (SPDT) mini-ISO automotive relay designed for high-current switching. It operates with a nominal coil voltage of 24VDC and includes a 2700 Ohm resistor in parallel with the coil. This relay is capable of switching up to 40A on its normally open contact and 30A on its normally closed contact, with a maximum switched voltage of 75VDC. It is designed to perform reliably in a wide operating temperature range from -40°C to 125°C. With its robust design, quick connect terminals, and high contact rating, it is suitable for various automotive applications such as controlling lighting, motors, and other heavy-duty loads.
