5. Tatūnga & Tāuta

Proper installation is crucial for the safe and efficient operation of the solid state relay. Refer to the wiring diagrams and follow these steps carefully.

5.1 Whakapiki

• Mount the relay on a flat, stable surface using screws through the designated mounting holes.
• For higher current models (e.g., 40A and above), it is highly recommended to use a heatsink to dissipate heat and prevent thermal damage. Ensure good thermal contact between the relay and the heatsink.
• Allow sufficient clearance around the relay for air circulation, especially if not using a heatsink.

5.2 Wiring Connections (DC Control DC)

The CDG1-1DD series is designed for DC control of DC loads. The input terminals (A1, A2) control the switching of the output terminals (L1, T1).

Figure 5.1: Connection diagram for DC control DC solid state relay (CDG1-1DD). Input is 3V-32VDC, output is DC-12V-220VDC.

1. Tāuru Mana (A1, A2):
   • Connect the positive (+) terminal of your DC control power supply (3V-32V DC) to terminal A1.
   • Connect the negative (-) terminal of your DC control power supply to terminal A2.
   • Kia tino tika te rōrahi whakahaeretage is within the specified range (3V-32V DC).
2. Load Output (L1, T1):
   • Connect the positive (+) terminal of your DC load power supply to terminal L1.
   • Connect one side of your DC load (e.g., motor, heater, LED strip) to terminal T1.
   • Connect the other side of your DC load to the negative (-) terminal of your DC load power supply.
   • Ensure the load voltage and current are within the relay's specified ratings.
3. Manatoko Hononga: Double-check all wiring for correct polarity and secure connections before applying power. Loose connections can cause overheating and damage.

6. Nga Tohutohu Whakahaere

Once properly installed and wired, operating the SOBOUR CDG1-1DD Solid State Relay is straightforward:

1. Apply Load Power: Ensure the DC load power supply is connected and ready.
2. Apply Control Signal: Apply the specified DC control voltage (3V-32V DC) to the input terminals (A1, A2).
3. Whakahohenga Relay: Ina te mana voltage is applied, the internal solid-state switch will close, allowing current to flow through the load circuit (L1 to T1), activating your DC load.
4. Relay Deactivation: Ina te mana voltage is removed from A1 and A2, the internal solid-state switch will open, interrupting the current flow to the load and deactivating it.

The relay operates silently and without mechanical wear, providing a fast and reliable switching action.

7. Tiaki

The SOBOUR CDG1-1DD Solid State Relay is designed for maintenance-free operation due to its solid-state nature. However, periodic checks can help ensure optimal performance and longevity:

• Tirotiro Ataata: Periodically inspect the relay for any signs of physical damage, discoloration (indicating overheating), or loose connections.
• Hononga Tikanga: Ensure all terminal screws are tight and wires are securely connected. Loose connections can lead to increased resistance and heat.
• Te ma: Keep the relay and its surroundings free from dust, dirt, and debris, which can impede heat dissipation. Use a soft, dry cloth for cleaning.
• Whakahaere Weariki: If a heatsink is used, ensure it is clean and free of obstructions. Verify that the ambient temperature remains within the relay's operating limits.
