NI FP-DI-330

Important note: For new designs, National Instruments recommends CompactRIO hardware (see Resources tab).

The NI FP-DI-330 module features eight universal digital input channels, each of which is compatible with 5 to 48 VDC sinking or sourcing signals and with AC signals up to 240 VAC. In addition, each channel features a differential two-wire input connection, which you can use to connect each channel to a different voltage level to measure 240 VAC and 24 VDC on the same module. Each channel also has two additional connections to the common voltage and common power distribution buses to make it easy to power external devices that use the same voltage levels. Lastly, each channel has an LED to indicate the channel on/off state.

The FP-DI-330 features 2,300 Vrms transient isolation between the output channels and the backplane. You can use these discrete input modules to sense the state of a variety of discrete devices - proximity and limit switches, push-button switches, thermostat outputs, relays, TTL, and power circuits. To make installation and setup easier, the FP-DI-330 features HotPnP (plug-and-play) operation, so it is automatically detected and identified by the configuration software. Note: Use the NI FP-CB-1 with hazardous voltages (greater than 42.4 V peak or 60 VDC).
