Carlo Gavazzi UK is expanding its portfolio of products for the water treatment market with the introduction of a new pump changeover relay.
The new compact, smart relay will successfully manage up to three alternating pumps, reducing maintenance costs and increasing efficiency.
The DLA71 from Carlo Gavazzi features a rescue function to manage overflow effectively and a delay setting to limit inrush current overloading the system.
The new relay is ideal for applications such as water treatment and HVAC systems where space is at a premium and two or three pumps need to be managed simultaneously.
The new changeover relay comes in a 35.5mm DIN-rail modular housing and operates from supply voltages of 24/48 or 115/230V AC.
To ensure reliable backup function and reduced maintenance the DLA71 offers differential or sequential working modes together with the ability to automatically alternate pump usage every six hours when continuous operation is required.
