Relay Interface De-Rating Process:
To ensure safe and efficient relay operation, determining an appropriate operating point involves several systematic steps:

1. Determine Maximum Simultaneously Energized Relays: Identify the maximum number of relays that will be energized simultaneously for more than a few minutes. This value is a fundamental parameter for establishing your operating point.

2. Locate Diagonal Bold Lines on the De-Rating Chart: Refer to the provided de-rating chart to find the diagonal bold lines corresponding to the number of "ON" relays. Identify lines both above and below your determined number of relays to form the basis for your operating point determination.

3. Horizontal Interpolation and Sketching: Horizontally interpolate between the identified diagonal lines to estimate temperature values between them. Sketch a line representing your interpolated value, or round up your relay count to match an available line for simplicity.

4. Determine Coil Voltage and Average Contact Current: Assess the supply voltage to the relay coils and calculate an average contact current, essential for defining your operating conditions accurately.

5. Find Corresponding Curves: On the de-rating chart, locate curves matching your determined coil voltage. These curves represent different combinations of coil voltage and contact current, aiding in visualizing operating limits for your application.

6. Estimate Average Contact Current Curve: Estimate a curve corresponding to your calculated average contact current, ensuring it aligns with your application's parameters and the specific coil voltage used.

7. Identify Intersection Point: Identify the intersection point between your estimated average contact current curve and the diagonal line representing the number of energized relays. This intersection point is crucial for determining your operating point.

8. Check for Safe Temperature: Ensure the intersection point's temperature value is below the critical limit of 55°C, guaranteeing safe temperature operation and preventing overheating or potential malfunctions in your relay application.
