Why Choose the Lovato HRA502CD024K4 Assembled Miniature Relay?
The Lovato HRA502CD024K4 is a complete assembled miniature relay and socket combination designed for industrial control, automation and auxiliary switching applications. It combines a 24 V DC coil, 2 changeover (2 C/O) contacts and an 8 A rated current with an LED state indicator and mechanical test actuator.
Supplied as an assembled solution, the HRA502CD024K4 incorporates a screw-terminal socket together with a retain/release clip, simplifying installation and relay replacement in control panels. The assembly can be mounted on a 35 mm DIN rail or fixed by screw, providing flexibility for industrial panel construction.
The relay uses Ag/Ni contacts and provides a rated insulation voltage of 250 V with a 6 kV impulse withstand voltage. A mechanical endurance of up to 10 million operations, visible LED indication and manual test actuator make it particularly practical for commissioning, diagnostics and maintenance.

Reliable and Service-Friendly Industrial Switching
The Lovato HRA502CD024K4 combines the relay and mounting socket into a ready-to-install assembly. Its two changeover contacts allow one 24 V DC control signal to operate two independent switching circuits, making it suitable for PLC interfacing, signal multiplication, interlocking and auxiliary control duties.
The integrated LED gives technicians an immediate indication of coil status, while the mechanical actuator and contact-position indicator assist during commissioning and fault finding. The retain/release clip securely holds the relay in its socket while still allowing straightforward replacement during maintenance.
Typical Applications
- Industrial control and automation panels.
- PLC input and output interfacing.
- Machinery auxiliary control circuits.
- Signal multiplication and interlocking.
- Contactor and motor-control circuits.
- Building automation systems.
- General-purpose electrical switching requiring an assembled relay and socket.
