AZ947-1C-24DE

Relay Automotive Overview

The AZ947-1C-24DE is a subminiature PCB power relay manufactured by American Zettler, designed for automotive applications. It features a single-pole double-throw (SPDT) contact configuration with one Form C switch. The device utilizes a 24VDC coil voltage and supports a maximum contact current of 20A. It is constructed for through-hole mounting on printed circuit boards. The relay is rated for switching voltages up to 250VAC and includes silver nickel contact material to ensure reliable electrical performance in high-current environments.
