Isolated DIO connector
The Isolated Digital Input/Output (DIO) connector provides
electrical isolation of digital input and output signals, which
allow micro controllers to detect and output logic states. The
high voltage protection can be used in industrial level uses.
Please refer to the illustration below for the specication and
pin denitions of the Isolated DIO connector.
