All About CAN Bus Devices

August 15, 2023

Controller Area Network (CAN) refers to a high-integrity serial communications protocol that facilitates interactions between electronic controls, sensors, and electromechanical devices in a system. The network standard accommodates the need for real-time control and secure transmission. While it was originally designed for use in vehicles, its ruggedness and dependability have led to its increasing employment…

Contactors and Relays 101 – Comparison & Applications

August 15, 2023

Contactors and relays are both solenoid switches that operate in electrical circuits to help ensure the efficiency of the system. They have similar functions and constructions, which results in many people confusing the two and even using the terms interchangeably. At a basic level, the two components function to turn electrical circuits on and off…
