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
