Lovato HRA502CA024K4 is an assembled miniature general-purpose relay with two 8 A changeover contacts, a 24 V AC coil, LED state indication, mechanical actuator and screw-terminal socket for industrial control and automation applications.
£23.08
The Lovato HRA502CA024K4 is a complete assembled miniature general-purpose relay designed for dependable switching and interface duties in industrial control and automation systems. It combines an HR502C miniature relay with a socket, LED state indication, mechanical actuator and retain/release clip, providing a convenient ready-to-install solution for electrical control panels.
This relay assembly features 2 C/O (DPDT) contacts rated at 8 A and a 24 V AC control coil. The Ag/Ni contacts provide reliable switching performance, while the integrated LED gives clear visual confirmation of relay status and the mechanical actuator supports convenient testing and commissioning.
The HRA502CA024K4 is supplied with a screw-terminal socket and can be installed on a standard 35 mm DIN rail or fixed by screw. Its complete assembled format reduces component selection and installation time, making it well suited to machinery, PLC interfaces, control cabinets and general industrial automation applications.
Miniature relays such as the Lovato HRA502CA024K4 allow low-power control circuits to operate separate electrical loads through electrically isolated changeover contacts. Its two C/O contacts provide normally open and normally closed switching paths, giving control engineers flexibility when designing interlocking, signalling, interface and auxiliary control circuits.
The complete assembled configuration combines the relay, LED indication, mechanical actuator and screw-terminal socket in one installation-ready unit. DIN rail mounting and accessible screw terminals simplify panel wiring, while the LED and mechanical indication features assist with commissioning, operation and fault finding.
