This Level Relays provides reliable liquid level control for water supply and drainage scenarios. It supports AC/DC 100~240V working power, fitting most electrical systems in industrial and domestic settings. It offers four working modes—water supply (ultra-high alarm type), drainage (ultra-high double-row type), drainage (ultra-low alarm type), and water supply (ultra-low self-locking type)—selected via short-circuit terminals to match different application needs. Its water control distance reaches up to 200 meters, enabling long-range liquid level monitoring and control without signal loss. It is equipped with two normally open contacts, with a contact capacity of 1A AC240V (resistive load), suitable for low-to-medium power control circuits.

With external dimensions of 24.5×85.5×90.5mm, the relay features a compact design that saves space in electrical cabinets or control panels. It supports two flexible installation methods: device-mounted (for direct integration with equipment) and 35mm DIN rail-mounted (for standard cabinet rails), adapting to different assembly environments. Whether for industrial water tanks, domestic water towers, or drainage systems, this Level Relays combines versatility, long-distance control, and easy installation, making it a practical choice for automated liquid level management.
