Introduction

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

 

selectable.

 

• 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

 

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 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'

 

commands)

 

• 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

 

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.
