Ethernet DPDT Relay

Network Relay Boards with DPDT Relays Installed

Double Pole Double Throw Relay

A DPDT Relay, Double Pole Double Throw Relay, has a single coil with two arms that move at the same time.  There are two completely separate SPDT switch mechanisms inside a DPDT relay.  A DPDT relay board is most commonly used for signal switching applications, but can be found in high power switching applications as well.

Computer Controlled Switching from Anywhere on the Network

An Ethernet Relay Board will Allow Computer Controlled Switching from Any Computer Connected to a 10/100 Ethernet Network. The Ethernet Relay Board Connects to the Ethernet Port of your Local Network Hub, Allowing Computer Controlled Switching from Anywhere on the Network.  Current versions offer Relay Control + 8-Channels 8/10-Bit A/D, or Relay Control + UXP Expansion Port.  All versions include an XR Expansion Port for adding additional relay banks.  Using our Standardized ProXR Command Set.

    Ethernet DPDT Communications

  • Ethernet Interface Mounts as a COM Port on your PC Through your LAN
  • Supports Telnet and Data Encryption with password protection
  • Embedded Digi Connect Wi-ME Ethernet Interface and Web Server from www.digi.com
  • Plug in, open the COM port and start sending commands
  • Control one relay at a time or all relays at once with manual and automatic refreshing command set
  • Control up to 256 relays
  • CPU status LEDs show command processing Activity
  • SignalSwitch Compatible
Simply connect this Ethernet Board to the Ethernet Port of your computer or to a networked Ethernet outlet and power up the device. In no time you'll be talking to the board and any attached Expansion Boards.
With no extra Programming you can talk to our Networking Boards via the Internet using SignalSwitch.com, without a dedicated computer for the board.

32 Channel Ethernet Relay Board

Ethernet DPDT Relay

Our Ethernet DPDT boards offer your choice of 1, 3 or 5 amp relays and are available in 4, 8 and 16 channel versions with your choice of eight channel 8/10-Bit Analog to Digital Conversion or UXP Expansion Port on selected models, look for AD or UXP in the part number. All are of course SignalSwitch compatible.  All Ethernet DPDT Relays feature the ProXR Command Set and an XR Expansion Port, simply look for PROXR in the part number.  The XR Expansion Port will allow you to expand any ProXR model board to 256 relays using our XR Expansion Modules.  The UXP port will allow you to add Analog to Digital Expansion Modules, Contact Closure Input Modules or Digital Potentiometers to any UXP board.  For more on A/D Conversion and UXP Expansion see below.

Easy Software Development

Communications and software development is very easy, simply write your software to speak to the RS-232 serial port (COM port of your PC), and install the included RealPort Drivers that allow you to map a COM port to an I.P. address. So you do not have to know anything about Ethernet communications to speak to the device.

Many Communication Protocols for Advanced Users

AdAdvanced users may want to employ other communication protocols to speak the the Ethernet Relay Controller. NCD Ethernet Relay Controllers can also be controlled using Telnet. I.P. Addresses and are automatically or manually assigned. NCD Ethernet Relay Controllers also support security protocols such as Shared Key, WEP, WPA, and Cisco LEAP with support for WEP, TKIP, and CCMP data encryption.

Wi-Fi 802.11b DPDT Available

We also carry a complete line of DPDT WiFi Boards!  A Wi-Fi Relay Board will Allow Computer Controlled Switching from Any Computer Connected to your Network.  Wi-Fi devices also supports Telnet and Data Encryption with Password Protection.  To view our Wi-Fi DPDT Boards please click here.

Ethernet Relay with Analog to Digital Conversion Ethernet Relay with UXP Expansion Port Ethernet Relay with XR Expansion Port

Onboard analog to digital conversion is available on selected models of these controllers! This will allow you to:

  • Read light and temperature levels
  • Easily activate relays when A/D limits are reached
  • Detect audio levels in a room when connected to a microphone
  • Read switches, potentiometers, and analog joysticks
  • applications are limitless, and surprisingly easy to integrate
  • Available on the 4, 8, and 16 channel boards

UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. UXP in the part number allows you to:

  • Add Contact Closure Inputs
  • Add Analog to Digital Inputs
  • Add Voltage Detectors
  • Digital Potentiometer Outputs
  • Available on the 4 and 8 channel boards

Models with the ProXR suffix will feature the ProXR commend set. The ProXR series will allow you to:

  • Send simple commands to activate relays
  • Upgrade without having to re-write your software
  • Activate up to 16 relay timers
  • Control up to 256 total relays using the XR expansion port
  • Full backward/forward compatibility w/the ProXR series command set
  • Available on all Ethernet DPDT  boards
