Infineon’s new series of solid-state isolators facilitate faster and more reliable switching in high-voltage electronics.

RelayFi is fitted with an ESP32-WROOM-32D WiFi and Bluetooth module, four relays capable of handling a load of 250 VAC/7A or 30 VDC/10A, and EL817C Optoisolators for safety. The board also comes with ...

Isolators are used to eliminate ground loops, and also to protect circuits that are sensitive to high voltages. Optoisolators are normally deployed for these purposes, but they suffer from several ...

Introduction In Industrial motor or servo control applications, accurate current measurement is a critical as part of the control loop. Not only has the ...

Also, if you’d like to control a few devices over the Internet, [Rob] included a few optoisolators for lights or appliances. The code is available on the 43oh forum page, but [Rob] says he’ll ...

So your electronic hobby skills are coming along quite nicely but you’re not very comfortable doing more than blinking a few LEDs. Now’s a good time to try something new by driving a co… ...

Delivering data rates up to 500 kb/s, the OPI1268 series optoisolators employ the Photologic phototransistor technology that enables temperature, voltage, and current compensation ...

Optoisolators are available in a multitude of package styles including rectangles, cylinders, and specialty configurations. These package types are designed to provide higher isolation voltages than ...

A decade or so ago, I designed a simple circuit that included a quad optoisolator arranged in a full-wave analog-multiplier bridge (Figure 1). It sensed and calculated watts of ac-power consumption ...

Existing single-loop feedback methods of linearization do not consider the conflicting aspect of linearity and longer lifetime of the LED's. In this correspondence, a multiple-loop feedback system is ...
