Basic information
• The active levels of all inputs and outputs are configured to "high active" by default
(customer-specific settings may differ).
• Through the digital inputs and outputs, it is possible to switch certain functions of
the PxtFX devices on or off and to evaluate status messages.
• The GND supply voltage and GNC digital signals must be directly connected.
Connectable
