NI-2000 Specifications (Cont.)

Rear Panel Connectors (Cont.):

Relay (Port 4)

Four-channel single-pole single-throw relay ports


• Each relay is independently controlled.


• Supports up to 4 independent external relay devices


• Channel range = 1-4


• Each relay can switch up to 24 VDC or 28 VAC @ 1 A


8-pin 3.5 mm mini-Phoenix (female) connector provides relay termination



Digital I/O (Port 9)

Four-channel binary I/O port for contact closure


• Each input is capable of voltage sensing. Input format is software




• Interactive power sensing for IR ports


• Channel range = 1-4


• All inputs are assigned to respective IR/Serial ports for "automatic" power


control through the use of software commands. Power control is provided


via commands such as: ’PON’, ’POF’, ’POD’, ’DELAY’, I/O Link etc.).


• Contact closure between GND and an I/O port is detected as a PUSH


• When used as voltage input - 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


• When used as an output - each I/O port acts as a switch to GND and is


rated at 200 mA @ 12 VDC


6-pin 3.5 mm mini-Phoenix (female) connector provides I/O port




Note: This IO port uses 5V logic but can handle up to 12V without harm. It


can handle up to 12V on the input. At higher voltages you run a higher risk of


surge damage.



IR/Serial (Ports 5-8)

Four IR/Serial control ports support high-frequency carriers of up to


1.142 MHz.


• Each output is capable of three electrical formats: IR, Serial, and Data


• Four IR/Serial data signals can be generated simultaneously.


• Channel range = 1-32,767


• Channels 1-128 (output): IR commands


• Channels 129-253: used as reference channels


• Channel 254 (feedback): Power Fail (used with 'PON' and 'POF'




• Channel 255 (feedback): Power status (when IO Link is set)


• IR ports support data mode (at limited baud rates and wiring distances).


8-pin 3.5 mm mini-Phoenix (female) connector provides IR/Serial port





Program port

RS-232 DB9 connector (male) can be connected to a DB9 port on a


computer; used with serial commands, NetLinx programming commands,


other DB9 capable devices, and to upload/download information from the


NetLinx Studio 2.4 program.



Configuration DIP switch

• Sets the communication parameters for the Program port.



ID pushbutton

• Provides the NetLinx ID (Device only) assignment for the device.


• The D notation is used to represent a device number.


• Refer to the NetLinx Integrated Controller WebConsole & Programming


Guide for details.



Ethernet port

RJ-45 port for 10/100 Mbps communication. This port automatically


negotiates the connection speed (10 Mbps or 100 Mbps) and whether to


use half duplex or full duplex mode.
