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.
