2.4.2 GPIO HARDWARE SPECIFICATION

4 X Relay isolated output:

• normally open contact (power off -> open)

• maximum 1A

• maximum 50 Volts

• typical life time: 100.000.000 switching

4 X Opto isolated input:

•

The input consists in an opto diode (VF @ 1.1 Volt) in series with a 470 ohm

resistor).

• Typical switching point @ 1.4 mA, for secure operation:

o i=0 to 0.5 mA -> opto OFF
