Product Overview
The RXM2LB2BD belongs to Schneider Electric’s Zelio Relay series. It is a small plug - in intermediate relay. As part of the Harmony electromechanical relays, this series of relays features a compact design and powerful functions. The RXM2LB2BD relay has a contact form of 2C/O (two normally open and two normally closed), a rated current of 5A, and a control circuit voltage of 24V DC. It is also equipped with a mechanical indicator, which visually shows the contact status of the relay through an orange flag. Meanwhile, the product has an IP40 protection level and a transparent cover, facilitating operators to visually inspect the contacts at any time. When the relay is working, the green LED on the front lights up, clearly indicating the working status both during the day and at night.
Working Principle
As an electromagnetic relay, the working principle of the RXM2LB2BD is based on the law of electromagnetic induction. When the coil is energized, a magnetic field is generated.
