Pack of 5 relays in the HF3FA family, including models HF3FA 005 ZSTF, HF3FA 012 ZSTF, and HF3FA 024 ZSTF. 5-pin power relays with coil voltages of 5V, 12V, and 24V. Current rating is 10A, with a maximum load of 250 VAC. Type: power relay designed for switching mains and automation circuits. Size: footprint follows HF3FA 024 ZSTF for the 24V model. Key benefits and why you need them - Flexible coil options: choose 5V, 12V, or 24V to match your control logic and drive electronics. - Robust switching: 10A rated current supports common AC loads up to 250 VAC. - Reliable power switching: ideal for enabling small to mid size automation tasks while keeping control logic separate from mains side. - Compact, consistent form: size aligned with the 24V variant ensures predictable panel layout and easy replacement. 2-3 practical use scenarios - Home automation: drive a mains-powered light or fan from a microcontroller using the 5V or 12V coil variants. - PLC or control panel: isolate control circuitry from mains to switch pumps, heaters, or sensors up to 10A and 250 VAC. - Small equipment control: manage AC appliances in an enclosure, such as fans or alarms, with a dedicated 24V coil system using the HF3FA 024 ZSTF footprint.
