£25.37
The Lovato HRA604CD024K4 is a pre-assembled industrial general purpose relay designed for reliable switching and control in industrial automation, machinery and electrical panel applications. Combining a 24 V DC relay with a screw-terminal socket, LED state indicator, mechanical actuator and retain/release clip, it provides a convenient ready-to-install switching solution.
Featuring 4 C/O changeover contacts and a rated current of 5 A, the HRA604CD024K4 provides flexible control of multiple circuits from a single relay. Silver tin oxide AgSnO2 contacts provide dependable electrical switching, while the integrated LED gives clear visual indication of relay status and the mechanical contact position indicator allows straightforward inspection.
The supplied screw-terminal socket supports installation on 35 mm DIN rail or by screw fixing, making the assembly particularly suitable for industrial control cabinets. With a 24 V DC control voltage, mechanical test actuator and long mechanical operating life, the HRA604CD024K4 is an effective solution for machine builders, panel builders and automation engineers.
Industrial relays such as the Lovato HRA604CD024K4 allow low-voltage control systems to switch multiple electrical circuits reliably. Its four changeover contacts provide both normally open and normally closed switching paths, making the relay suitable for interlocking, signalling, sequencing and general automation functions.
The HRA604CD024K4 is supplied as an assembled relay and socket combination, reducing component selection and installation work. Its LED state indicator, mechanical contact position indicator and test actuator assist with commissioning and fault finding, while the screw-terminal socket enables secure wiring and straightforward DIN-rail integration inside industrial control panels.
