GENERAL I/O
General I/O provides analog input as well as digital output. Each General I/O port can be used either as input
or as output.
Pull-up resistor 680 ohms is connected to +5 VDC and can be switched on and off for each I/O
independently. I/O voltage with pull-up on is approx. +4.3 VDC, because protection diode is connected in
series (0.7 V dropdown).
Analog input is rated 0 – 5 VDC. Analog to digital (A/D) converter has 10-bits precision (i.e. 1024 levels).
Digital output can switch max. 24 VDC / 80 mA. Output voltage for output switch on is approx. 0.6 V.
