Overview
The Continental SVDA-6V50 is an industrial-grade solid state relay engineered for switching and control applications. With a 50A output rating at 600VAC and a 4-32VDC control input, this panel-mount unit provides reliable low-EMI switching for motors, solenoids, heating elements, and other electrical loads in manufacturing, HVAC, and process control environments.
Key Features
- 50A output rating at 600VAC (hockey-puck form factor with industry-standard footprint)
- 4-32VDC control input range for flexibility with PLC and controller logic outputs
- Zero-crossing switching technology reduces dv/dt stress and EMI on AC circuits
- Anti-parallel thyristor output handles resistive, inductive, and capacitive loads
- Built-in transient protection and varistor for harsh industrial environments
- LED status indicator for control input verification
- Clip-on cover providing IP 20 touch protection
