TS-15120 Specifications

Conditions

Specifications are typical under the following conditions unless otherwise noted.

  • Ambient temperature of 0 °C to 55 °C. The ambient temperature is defined as the temperature at the enclosure fan inlet (air intake). Refer to the Thermal Considerations topic in the backplanes documentation on ni.com/docs for additional information on ambient temperature characteristics and cooling requirements.
  • All voltages relative to COM.

Input/Output Characteristics

Number of channels

32 digital input/output channels

Input/output type

5 V/3.3 V TTL, single-ended

Default power-on line direction

Input

Module output current

64 mA maximum

Note Module output current is the maximum guaranteed current that the module can drive from all the I/O lines without going into an overcurrent state.

Input capacitance

30 pF typical

Timing
Input

Setup time

10 ns minimum

Hold time

60 ns minimum

Output

Propagation delay

330 ns maximum

Channel-to-channel skew

265 ns maximum

Input read/output write time

7 μs minimum

Direction change time

18 μs minimum

Note Input reads and output writes are hardware timed and can be performed at rates up to ~142 kSamples/s (all inputs read and all outputs written once every 7 μs). Direction changes are always software timed and require 18 μs, minimum, in addition to system-dependent software latencies.

The following list provides additional information on the input/output specifications:

  • Setup time is the amount of time input signals must be stable before reading from the module.
  • Hold time is the amount of time input signals must be stable after initiating a read from the module.
  • Propagation delay is the amount of time after writing to the module that the output signals become valid.
  • Channel-to-channel skew is the amount of time between the first output signal updating and the last output signal updating.

Overvoltage protection, Channel-to-COM

±30 V maximum on 1 channel at a time

Notice Continued use at the maximum overvoltage protection level will degrade the life of the module.
