Let’s start with a inductive loads and how they interfere with USB connectivity:  Inductive loads are high voltage or high current loads that involve a

There are many ways to talk to USB relay controllers, some manufacturers choose HID or Custom USB communications to gain a performance advantage.  HID USB

One of the biggest tech support questions and problems we have seen with all relay controllers (not just USB) is the unusual expectation that relays

Imagine you want to use a USB relay controller to control a heater, or maybe you want to control a water pump for irrigation applications.

Being a relay controller manufacturer means we have to answer to customers when things go wrong.  When it comes to power, there are plenty of

Mechanical relays are clearly better than solid state-relays…but not really.  The fact is, you need to consider your application and your budget carefully before you

Controlling High-Power loads with the USB port is best accomplished with a combination of a large mechanical relay called a contactor and a solid-state relay

I could not even begin to guess how many relays we have sold over the years.  Relay failures are extremely rare for both mechanical and

The speed of a relay switching operation will help define the lifespan of the relay.  Mechanical relays often have a activation time of 5-10ms, with

Manual and computer control is a basic function built into all USB relay controllers we have manufactured for many years.  Manual control allows you to

We do not believe in hardware that goes obsolete.  We are strong proponents of building controllers that last for many years, not disposable devices that

USB Relay control is a relatively broad term.  We have created many devices that help focus USB relay control into a more specific application.  Here
