For the outputs opto-isolated solid-state relays are used. The two pins are depicted
as ”GPI Out x” and ”GPI Out x ~” respectively. The maximum current is: 0.3 A.
For the Inputs opto-isolators with anti-parallel LEDs are used. The two pins are de-
picted as ”GPI In x + ” and ” GPI In x -”. Plus and minus show the recommended
polarity. The inputs have an internal resistor of 1.0 kOhm. The maximum current
is: 40 mA.
