Note:
When driving an inductive load (for example, an external relay), a protection diode
must be connected in the correct polarity to prevent possible switch damage due to
inductive spikes generated by switching the inductor (please refer to instruction
manual). Intrinsically Safe Models - please follow local regulations and area
classifications; refer to instruction manual for more details.
