5.2 Digital I/O (DIO) Hardware Specification
•
XCOM+ : Isolated power in V+
•
XCOM ‐ : Isolated power in V ‐
•
Isolated power in DC voltage : 5 ~ 48V
• 4 x Digital Input (Source Type)
• Input Signal Voltage Level
- Signal Logic 0 :
XCOM+ =
5V, Signal Low - V- < 0.4V
XCOM+ >
5V, V+ - Signal Low > 4.6V
- Signal Logic 1 : > XCOM+ - 3V
• Input Driving Sink Current :
- Minimal : 1 mA
- Normal : 5 mA
• 4 x Digital Output (Open Drain)
- DO Signal have to pull up
resistor
to XCOM+ for external device, the
resistance will affect the pull up current
- Signal High Level : Pull up resistor to XCOM+
- Signal Low Level : = XCOM-
- Sink Current: 1A (Max)
