Relay Connections; Input/Output (I/O) Connections And Wiring - AMX NetLinx Integrated Controller NI-4000 Instruction Manual

Relay connections

Use A for common and B for output (FIG. 14). Each relay is isolated and normally open. A metal
connector strip is also provided to common multiple relays.

Input/Output (I/O) Connections and Wiring

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

FIG. 15 INPUT/OUTPUT connector (male)
You can connect up to eight devices to the I/O connectors on the NI-4000/3000 (four on the
NI-2000) (FIG. 15). A contact closure between GND and an I/O port is detected as a Push. When
used for voltage inputs, the I/O port detects a low (0-1.5 VDC) as a Push, and a high (3.5-5 VDC)
signal as a Release. When used for outputs, the I/O port acts as a switch to GND and is rated at 200
mA @ 12 VDC. The PWR pin (+12 VDC @ 200 mA) is designed as a power output for the PCS2
or VSS2 (or equivalent). The GND connector is a common ground and is shared by all I/O ports.
The following table lists the wiring specifications for the I/O connectors.
NetLinx Integrated Controllers
A metal commoning strip is supplied with each Integrated Controller to connect multiple
relays.
