If used with an external relay, a diode must be connected in parallel with the load, for protection against voltage transients. Max load = 100mA Max voltage = + 40V DC ENGLISH Page 14 AXIS Q7401 Installation Guide The following connection diagram gives an example of how to connect an auxiliary device to the AXIS Q7401. 1 2 E.g. push button I/O 3 configured as input I/O 4 configured as output AXIS Q7401 3.3V *12V max 100mA D S G * Note: Same voltage as pin 2 of the power connector AXIS Q7401 Inst
