If an overcurrent condition is detected, the electronic circuit limits or cuts off power to that specific channel and can report the fault to the controller for diagnostics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Is it suitable for safety applications?\u003c\/strong\u003e\u003cbr\u003eA\u0026gt; While it offers robust isolation, it is not a certified safety module.
