4. Product use instructions
Preparation before installation:
Check the appearance of the relay module for defects such as breakage, deformation, oxidation or bending of the pins, etc. If there are any problems, contact the supplier for replacement in time to ensure that the quality of the SSR solid state relay used is intact and undamaged.
Determine the installation position of the relay according to the actual application scenario and the requirements of the control system, and prepare suitable installation tools, such as screwdrivers, spanners, pliers, heat sinks (if required), etc. Ensure the precision and applicability of the tools to avoid damaging the relay in the installation process. At the same time, make sure that the installation environment is in line with the working conditions of the relay, avoiding high temperature, humidity, strong magnetic field and other unfavourable factors that may affect its performance.
Installation and connection:
Mount the solid state relay on a suitable heat sink (e.g. metal heat sink). If the operating current is high, good heat dissipation conditions are essential to ensure that the relay operates within the normal operating temperature range. Use screws to secure the relay to the heat sink, taking care not to over tighten as this may damage the relay case.
According to the pin definition of the relay and the electrical connection requirements of the control system, connect the control signal input terminal (corresponding to 3 - 32V DC control voltage) to the control source and the load terminal (connecting DC or AC load according to the application scenario) to the corresponding electrical equipment using wires of suitable specifications, paying attention to the correctness and firmness of the wiring, avoiding problems such as connecting the wrong wires, false connections or short-circuits. After the wiring is completed, check whether all the connections are firm and reliable, and make sure that the wires are not damaged and have good insulation to prevent malfunctions caused by poor electrical connections.
