SSR-25DD Solid State Relay
Key Features
- Control Method: DC to DC (DC Input, DC Output)
- Input Control Voltage: 3-32V DC
- Output Load Voltage: 5-200V DC
- Maximum Load Current: 25A
- Response Time: ≤10ms
- Dielectric Strength: >2.5KV
- Design: No moving parts for silent operation and extended lifespan. Features an isolated baseplate for efficient heat dissipation.
Replaces / Cross-Reference Part Numbers
- SSR-25DD
Compatibility & Fitment
- Suitable for switching high-current DC loads using a low-voltage DC control signal.
- Common applications include industrial automation, CNC machinery, DC motor control, DC heating elements, and robotics.
- Compatible with output signals from microcontrollers such as Arduino, Raspberry Pi, and other PLC systems.
When to Replace
- The relay fails to activate the load when a control signal is present.
- The load remains permanently on, even without a control signal.
- Switching becomes intermittent or unreliable.
- The relay overheats excessively during operation, indicating internal failure.
- Visible physical damage, such as cracks, burns, or melted housing.
Installation Tips
- Disconnect all power sources before installation or service.
- A heat sink is required for load currents exceeding 10A to ensure proper thermal management and prevent overheating.
- Apply a thin layer of thermal paste between the relay's metal base and the heat sink for optimal heat transfer.
- Ensure all wire connections are secure to prevent poor contact and potential arcing.
- Verify correct polarity for both the DC input (control) and DC output (load) terminals.
