Overview
The Continental SVDA-6V50 is a single-phase, panel-mount solid state relay designed for high-current switching applications. Rated for 50 amperes at 600VAC, it accepts DC control logic (4–32Vdc input) and uses zero-crossing switching technology to minimize electromagnetic interference and extend component life. Its rugged construction, transient protection, and fast switching response make it suitable for controlling resistive, inductive, and capacitive loads in industrial machinery, temperature control systems, and power distribution panels.
Key Features
- High current rating: 50A at 600VAC output for demanding industrial loads
- Zero-crossing switching: Reduces EMI and mechanical stress compared to mechanical relays
- 4–32VDC control: Industry-standard low-voltage logic input compatible with PLC and controller outputs
- Built-in transient protection: MOV-based surge suppression rated at 800V peak blocking voltage
- Panel-mount design: Compact footprint with high touch-protection (IP 20 with optional cover)
- No moving parts: Eliminates arcing contacts and mechanical wear for extended service life
