This file type includes high resolution graphics and schematics when applicable. According to the research firm IHS Inc., about 54 million relays and timers were purchased in 2013, a number projected ...

ABB has installed more than 700,000 SPACOM relays used for power system protection and reliable power system operation world-wide. With the older generation of relays now aging, ABB is developing new ...

MicroMax’s M-Max 400 RC is a highly reliable computer for building all-electric interlocking distributed systems. The system converts CAN-interface control signals (twisted pair or single-mode fiber) ...

Schweitzer Engineering Laboratories, Inc. (SEL) has announced wide-area-measurement-based control in a transformer relay for the first time. This enhancement to the SEL-487E Transformer Protection ...

SCADA cybersecurity protects grid control systems from unauthorized commands, data manipulation, and operational disruption. Without proper authentication, encryption, and network segmentation, ...

Differential protection is best understood as a fault control philosophy rather than a component category. The relay itself is secondary to the scheme it enforces. Once a zone is defined, the system ...

RF coaxial SPDT relays address signal-routing applications that demand a combination of high frequency, high power, and excellent RF performance. What role does an SPDT relay play in test applications ...

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...

This 12V solar charge regulator meets most small-scale application requirements. With a current rating of 6A, it can handle up to a 100W solar panel. Its principle of operation is very simple and ...
