    57 µs

    Single or dual input with test pulses

    165 µs

    spd-note-note
    Note

    Single input

    20 µs

    Dual input

    122 µs

    Single input with test pulses

    346 µs

    Dual input with test pulses

    649 µs

    spd-note-note
    Note

    Digital Output

    Output type

    Sourcing

    Minimum ON time

    190 μs

    spd-note-caution
    Caution  

    You must enforce minimum ON time or the channel may fail to de-energize in an overcurrent or short-circuit condition. Failure to de-energize in an overcurrent or short-circuit condition may damage the module.

    Minimum OFF time

    170 μs

    spd-note-caution
    Caution  

    You must enforce minimum OFF time except when the channel is configured with test pulses. Test pulse width may be smaller than the minimum OFF time.

    Continuous output current (per channel)

    250 mA, maximum

    spd-note-note
    Note  

    Transient loads exceeding overcurrent protection will trigger an overcurrent fault. This does not apply to inrush currents required to drive the specified load capacitance and cable length.

    External Power Supply Requirements

    spd-note-caution
    Caution  

    You must use an appropriate power source to limit output power in case of a fault. For a list of required power supply categories, refer to the C Series Functional Safety Manual on ni.com/manuals.

    Voltage input range

    19 V DC to 30 V DC

    spd-note-note
    Note  

    The NI 9350 includes input power protection circuitry. If the voltage at Vsup falls outside the voltage input range, the module will power down and all channels will de-energize. You must cycle external power to the module to resume operation.

    Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

    spd-note-caution
    Caution  

    Do not connect the NI 9350 to signals or use for measurements within Measurement Categories II, III, or IV.

    spd-note-note
    Note  

    Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
