An Engineer Explains the Hexadecimal and Octal Number Systems

An Engineer Explains the Hexadecimal and Octal Number Systems

Computers understand values as long strings of binary bits, but we humans convert them to other systems for convenience. Decimal makes sense, but what about hexadecimal and the lesser-known octal systems?


How To Use Analog Inputs With 2, 3, and 4 Wires

How To Use Analog Inputs With 2, 3, and 4 Wires

Analog inputs are used to measure changes in process through sensors, subsequently converting that signal to voltage or current and sending it to modules that measure this change to determine new setpoints.


Understanding Sensor Specifications

Understanding Sensor Specifications

Operating voltage, linearity, dimensions, polarity protection, range… When it comes to sensors, every situation calls for understanding these specs in detail during design, purchasing, and installation.


Introduction to Basic Three-Phase Motor Control Circuits

Introduction to Basic Three-Phase Motor Control Circuits

Large motors require a circuit to turn on and off. This may be as simple as a single on/off drum-type switch or as elaborate as a VFD unit. Learn about some common control circuit designs for typical three-phase motor requirements.
