Harmony Solid-State Relays
Schneider Electric’s Harmony solid-state relays are available in slim interface, DIN-rail-mount, or panel-mount
Schneider Electric's Harmony solid-state relays offer high switching frequency for precise and quick control, long lifetime, and silent operation. The complete product range offers slim interface (SSL), modular DIN-rail (SSD, SSM), and panel-mount (SSP) solid-state relays that provide compact and innovative solutions for a wide variety of applications with interfacing control and load switching. They are the ideal solution for packaging, plastic molding, textile, and furnace applications.
- Current ratings: 0.1 A to 124 A
- Simplified installation and mounting
- Flexible and robust wiring
- Easy debugging and commissioning
- Wide range of standards and certifications
- SSD range complies with IEC 61373 and IEC 60947-4-3
- Maintenance-free: no arc or intermittent contact issues as there are no moving parts
- Fast frequency switching: switch ON/OFF very fast, allowing precise and quick control
- Silent and reliable switching: noiseless switching makes it ideal for commercial and medical applications
- Shock and vibration resistant: without movable parts, the solid state relays do not bounce electrically or mechanically
