The RSL1PVJU is a pre-assembled plug-in relay with a socket from the Harmony Electromechanical Relays series, designed for use as a slim interface relay. It operates with a 12V AC/DC control circuit voltage and includes an integrated status LED for visual feedback. The relay features a single changeover (1 C/O) contact with a conventional enclosed thermal current rating of 6A and a maximum switching voltage of 277V. It offers high reliability with a mechanical durability of 10,000,000 cycles and a dielectric strength of 4000V AC between the coil and contact. Thanks to its slim 6.2 mm width and 35mm DIN rail mounting, the RSL1PVJU is ideal for space-constrained industrial control panels and automation systems.
