- Page 4 NI-9476 Getting Started Vsup Protection – Device NI 9476 The NI-9476 has sourcing outputs. Sourcing outputs drive current from ■ Vsup to DO when the channel is on. For more information about sourcing outputs, visit ni.com/info enter the Info Code sinksource.
- Page 5 You must connect an external power supply with a 6 V DC to 36 V DC voltage range to the NI-9476. This power supply provides the current for the devices you connect to the module. You can connect only one external voltage supply to the NI-9476.
- Page 6 I/O Protection The NI-9476 is protected against overcurrent, inrush, and short-circuit conditions in accordance with IEC 61131-2. Each channel on the NI-9476 has circuitry that protects it from voltage and current surges resulting from short circuits. Caution The NI-9476 can be damaged under overvoltage and reverse bias voltage conditions.
