Long Range Wireless Sensors

Our long range wireless enterprise series sensors are an easy to use and reliable start to any data aggregation application. This video will demonstrate how they work, what they do, and how to use them.

Node Red MCP23008 Timer Tutorial

In this video we will use NCD’s MCP23008 Node Red module.  We will trigger a relay for a specified duration using out of the box functionality in Node Red.A quick introduction to using NCD’s MCP23008 Node Red module.  In this video we used the following hardware:

4- Channel General Purpose SPDT Relay Shield + 4 GPIO with IoT Interface

USB Interface Adapter for NCD IoT Devices

Node Red MCP23008 Introduction

A quick introduction to using NCD’s MCP23008 Node Red module.  In this video we will install the ncd-red-mcp23008 module, configure it for use, and get some initial use out of it by turning a relay on and off.  In this video we used the following hardware:

Users may easily replace the USB interface for other technologies, such as RS-232, Ethernet, Wifi, Bluetooth, and many industrial wireless solutions. UXP and XR Expansion Ports allow high-resolution analog to digital conversion, contact closure inputs, and potentiometer outputs.

24-Channel Relay Controller with USB Modular Interface and Expansion Port

This 24-Channel USB relay board has a modular USB interface, compatible with Digi XBee modules, as well as Ethernet, Wifi, Bluetooth, RS-232 and other communication options. This video shows the UXP expansion port, with the ability to monitor high-resolution 12-Bit Analog to Digital Converters, Contact Closure Inputs, and Potentiometer Outputs. This controller is expandable to control more relays.

8 Channel USB Solid State Relay Controller ProXR Lite Hardware Overview

USB Solid State Relay Controllers make it easy to control high-power loads using highly reliable solid state switching technology. We use the FTDI FT232RL USB to Serial Converter to establish a Virtual COM Port Connection using Mac, Linux, or PCs. Integrated Analog to Digital Converters make it easy to read external sensors or manually control the On-Board Relays.

USB Relay Board 1-Channel 20A SPDT ProXR Lite Hardware Overview

This overview shows the hardware features of the ProXR Lite 1-Channel 20A USB relay board, ideal for computer controlled switching applications. This controller has many hardware features, including an extensive relay control command set, including flashers and timers, built-in A/D converters, and the ability to manually control the on-board relay with the ADC inputs. This is the USB version, but users may change the USB interface to other communication technologies, such as RS-232, Bluetooth, WiFi, Ethernet, and industrial wireless. We have a IoT communication module on the way, keeping ProXR controllers at the top of the list for best relay boards in the world.

USB Relay Board 1-Channel 10A SPDT ProXR Lite Hardware Overview
