Introduction

NI-2000, NI-3000, NI-4000 Hardware Reference Guide

NI-3000 Specifications (Cont.)

Rear Panel Connectors (Cont.):

Relay (Port 8) • Eight-channel single-pole single-throw relay ports

• Each relay is independently controlled.

• Supports up to 8 independent external relay devices

• Channel range = 1-8

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

• Two 8-pin 3.5 mm mini-Phoenix (female) connectors provide relay

termination

Digital I/O (Port 17) • Eight-channel binary I/O port for contact closure

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

selectable.

• Interactive power sensing for IR ports

• Channel range = 1-8

• 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

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

termination

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 9-16) • Eight IR/Serial control ports support high-frequency carriers up to

1.142 MHz

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

• Eight 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'

commands)

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

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

• Two 8-pin 3.5 mm mini-Phoenix (female) connectors provide IR/Serial port

termination

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.
