The RSL1AB4BD is a standard slim interface plug-in relay from the Harmony Electromechanical Relays RSL series. It operates with a 24V DC control circuit and features a single changeover (1 C/O) contact made of a silver alloy (AgSnO2). The relay is rated for a conventional enclosed thermal current of 6A, has a maximum switching voltage of 277V, and a maximum switching capacity of 1500 VA / 150 W. With a high dielectric strength of 4000V AC between coil and contact and an operating time of 12 ms, it ensures robust performance. Its compact 5mm width and flat pins make it ideal for PCB or socket mounting in space-constrained automation panels and control systems.
