The CARLO GAVAZZI DLA71DB232P is a versatile pump alternating relay designed to manage multiple pumps in a system. It allows for the activation of two or three pumps, with the option to activate a second or third pump in case of need, such as overflow situations. The relay incorporates a built-in delay to prevent high inrush currents when multiple pumps start simultaneously. It also features automatic pump rotation after a set period (6 hours) to distribute operating time and extend pump lifespan. This relay is commonly used in applications such as basin emptying, where it can be configured to operate in various modes, including differential mode for independent pump control. The DLA71DB232P is DIN rail mountable and offers robust protection and reliable performance for industrial pump management systems.
