Slim Integrated Solid State Relay | Din Rail Mount SSR 10A-120A with Heat Sink

DIN Rail Mount Solid State Relay is a slim integrated SSR with built-in heat sink, designed for compact industrial control cabinets and DIN rail installation. It supports high-efficiency switching for AC load control, with current options from 10A to 120A. The integrated heat sink improves thermal management, while the slim structure helps save panel space.

  • Modular, compact form factor with integrated aluminum heat sink for efficient heat dissipation
  • Wide load voltage compatibility: 24–480VAC for AC loads, 5–220VDC for DC loads
  • Control voltage ranges: 3–32VDC (DA and DD types), 70–280VAC (AA type)
  • Low on-state voltage drop ≤1.5 V, minimizing conduction losses and improving energy efficiency
  • Rapid switching with response time ≤10 ms for precise control
  • Low off-state leakage current ≤2 mA, ensuring safe operation
  • High insulation resistance ≥1000MΩ, ensuring electrical isolation
  • Robust dielectric strength rated at 2500VAC between input and output
  • Operating ambient temperature range: -30°C to +75°C for reliable performance in harsh environments
  • Secure DIN rail mounting with screw fasteners for vibration resistance and ease of installation
  • Status indicator LED for real-time switching state monitoring
