7.11. DIGITAL I/O
Digital I/O provide digital input as well as digital output. Each Digital I/O port can be used either as input or as
output.
Digital I/Os are applicable as follows
• DIGITAL I/O 1 - 12 on ipCUE-sigma
and not applicable for ipCUE-alpha, ipCUE-beta, ipCUE-gamma, ipCUE-delta, ipCUE-epsilon.
Pull-up resistor 680 ohms is connected to +5 VDC. Digital input is rated 0 – 24 VDC, threshold is 2 V. Voltage
on I/O with open output transistor is approx. 4.3 VDC, because protection diode is connected in series (0.7 V
drop-down). Voltage on I/O for output switch on is approx. 0.6 V. Max. 24 VDC / 80 mA can be switched by
output transistor.
