Overview

The Carlo Gavazzi DLA71DB232P is a 2-pump alternating relay engineered for duplex pump systems requiring balanced runtime and automatic rotation. The DLA71 series features a built-in 10-second delay for sequential pump activation, preventing large inrush currents during simultaneous starts. It includes LED indicators for power supply and relay status, with green steady for power on, 1 Hz flashing for one pump active, and 2 Hz flashing for two pumps active. The unit provides 2 x SPST NO relays rated at 5 A @ 250 VAC (AC-1 resistive load) and 5 A @ 24 VDC (DC-12), supporting small inductive loads up to 1.5 A @ 250 VAC (AC-15) and 1.5 A @ 24 VDC (DC-13). The relay supports differential or sequential modes, enabling automatic rotation of pumps every 6 hours of continuous operation to ensure uniform wear. It is suitable for emptying or filling basins in 2-pump systems, with rescue functionality activating a second pump if needed.
