3.3 V DC	2	Can be used to power auxiliary equipment.	Max load = 50 mA
Power		Note: This pin can only be used as power out.
Digital	3	Connect to GND to activate, or leave floating	Min. input = -40 V DC
Input		(unconnected) to deactivate.	Max. input= +40 V DC
Digital	4	Uses an open-drain NFET transistor with the source	Max. load =100 mA
Output		connected to GND. If used with an external relay, a	Max. voltage = + 40 V DC	ENGLISH
		diode must be connected in parallel with the load,
		for protection against voltage transients.
