Function: 1. EASY TO INSTALL: Solid state relay uses a standard 35MM DIN rail installation method with a DIN rail installation buckle at the bottom, making disassembly and installation faster and safer. 2. WITH HEAT SINK: Solid state relay features a thickened heat sink design made of aluminum material, which instantly absorbs and dissipates heat generated by the module during operation. 3. LONG SERVICE LIFE: The heat sink can reduce long-term thermal fatigue of DC to DC solid state relay modules and extend equipment lifespan, allowing for confident use. 4. SENSITIVE AND LOW NOISE: Single-phase SSR offers benefits like erosion resistance, low input power, high sensitivity, good electromagnetic compatibility, low noise, and operating frequency. 5. STABLE AND RELIABLE: DIN rail solid state relay utilizes excellent chips with LED indicator lights for more stable operation and strong anti-interference capabilities.
