Relay Connections; Input/Output (I/O) Port: Connections And Wiring - AMX NetLinx NI-3101-SIG Operation/Reference Manual

Connections and Wiring

Relay connections

Use A for common and B for output (FIG. 8). Each relay is isolated and normally open. A metal
connector strip is also provided to common multiple relays.

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

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

FIG. 9 INPUT/OUTPUT connector (male)
Up to eight devices may be connected to the I/O connectors on the NI-3101-SIG (FIG. 9). 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
200 mA @ 12 VDC. This device 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.
