[PDM 25] Activation of High-Current Loads (Over 30A)
We need to operate high-current devices (e.g., $40\text{A}$ starter motor solenoid, high-flow fuel pumps) that exceed the $10\text{A}$ and $20\text{A}$ continuous limits of the PDM's individual outputs.
What is the recommended method and corresponding PDM logic to activate a large external relay (e.g., $40\text{A}$ or $70\text{A}$ capacity)?
We intend to use a low-current PDM output (e.g., $10\text{A}$ output) only to supply power to the coil of the external relay, allowing the relay to handle the full load current directly from the main battery.

You can pair outputs for greater amperage. Make sure the configs are identical.
If you prefer to have an external relay, wire your output to the 86 and ground 85. Add your logic to turn on relay.
