Schneider Harmony RSL Slim Interface Relays

Schneider Harmony RSL Slim Interface Relays are compact electromechanical relays designed for PLC interfaces, industrial automation, and machine control applications where panel space is limited. Their slim profile allows more relays to be installed on a DIN rail without compromising switching performance, making them a practical choice for modern control cabinets.

The Harmony RSL series provides reliable electrical isolation between low-power control signals and field devices such as contactors, solenoid valves, alarms, and indicator lamps. Available in multiple AC and DC coil voltage options, these relays support fast installation and easy replacement through their plug-in design.

Many models feature an LED status indicator and manual test lever, allowing operators to verify relay operation during commissioning and maintenance. Harmony RSL relays are compatible with Schneider relay sockets and accessories, making them suitable for both new automation projects and panel upgrades.
