Input/Output (I/O) Port: Connections and Wiring

The I/O port responds to either switch closures, voltage level (high/low) changes, or it can be used for logic-level outputs.

FIG. 7 INPUT/OUTPUT (I/O) connector (male)

A contact closure between the GND and an I/O port is detected as a Push.

When used for voltage inputs, the I/O port detects a low signal (0 - 1.5 VDC) as a Push, and a high signal (3.5 - 5 VDC) as a Release (this IO port uses 5V logic but can handle up to 12V without harm).

When used for outputs, the I/O port acts as a switch to GND and is rated for 200mA @ 12 VDC.

The NI-2000 can use up to 4 I/O ports

The NI-3000 and NI-4000 can use up to 8 I/O ports

The PWR pin provides +12 VDC @ 200 mA and is designed as a power output for the PCS Power Current Sensors, VSS2 Video Sync Sensors (or equivalent).

The GND connector is a common ground and is shared by all I/O ports. A common ground is shared with I/O ports 1 - 8 (NI-3000/NI-4000) or with I/O ports 1 - 3 (NI-2000).
