Wireless Relay Board

Wireless Relays are equipped with firmware built into the board that will allow you to Control one relay at a time, a bank of relays or all relays at once with manual and automatic refreshing command set.  Wireless Relay Controllers allow wireless computer controlled switching and mount as a COM port on your computer.  Wireless Relays are ideally suited for applications that require data collection and control from a single device.

Wireless Relay Overview

Wireless Protocols for Today's Needs

National Control Devices offers more wireless options that any other relay manufacturer.  Each wireless protocol has a place and we're confident that you will find one to suit your application  Here's an overview of each wireless protocol we offer.


We offer Bluetooth communications because of its popularity with mobile devices. If you want to control relays with your smartphone (and you are savvy at writing such an application), then Bluetooth is the ideal choice. iPhone, iPad, and iPod developers should be warned, Apple iOS devices encrypt the Bluetooth protocol deliberately, so our Bluetooth interface is compatible with every computer ever made, including Android, PCs (and every version of Windows that supports Bluetooth), and Linux (and all variants thereof that support Bluetooth), but it will NEVER work with Apple iOS devices... (Yes, we get this question all the time....)

802.15.4 Point to Point Wireless

This is one of our favorite wireless technologies. It is easy to setup and use and very reliable. You need a 802.15.4 modem that plugs into your USB port to talk any number of 802.15.4 Wireless relays with up to 1 mile range!  You can purchase a modem with the device you choose.


Much of our development work was done with embedded Wi-Fi. Put simply, we adore this technology and we think you will too. Con-figuration requires careful attention to our instructions, but once configured...wow. It's simply amazing and holds so much promise for future development work. We are working to make configuration easier, but for now, plan on reading our manual found on the product pages BEFORE purchasing....the configuration process is not for everyone.

XSC Long Range Wireless

A fantastic wireless technology that goes a long way...up to 15 miles (though we have never seen it go this far). XSC has the distinction of being the longest range wireless technology we offer, though it is limited to 57.6K Baud, it is very reliable.

ZigBee Mesh Wireless Networking

ZigBee Mesh networking is pretty slow, but extremely powerful and very reliable when you follow all the rules. We highly recommend you purchase a ZigBee Development Kit from www.digi.com before attempting to use this communication technology...this one is for the advanced user. But it has the distinction of offering a low-cost Mesh networking protocol...which means wireless data hops around the wireless network until it reaches the destination device...very cool! Very powerful, very long range, but NOT for the timid.
