Control.com’s Director of Engineering got to explore IO-Link sensors and what he found might surprise you! Although still considered an “emerging” technology, it’s clear IO-Link technology boasts several bonafide benefits over traditional sensors.

Variable control allows external conditions, like temperature, to be monitored so the controller can activate devices to heat or cool the system as needed. Simulate a temp controller with low-cost components!

Designing, installing, and maintaining control systems involves a lot of wires. Each wire has a purpose, often indicated by the color of the insulation. But what are the common colors, and what do they mean?

Most engineers are familiar with the basic control system terms of sinking and sourcing, or the NPN and PNP terms from which they are derived. But how exactly do those transistors play a role in inputs or outputs?

We are taught that parallel circuits maintain equal voltage across all branch resistors, equally sharing the source voltage. But reality is often far from ideal, and individual devices certainly impact the rest of the circuit.

You are bound to encounter two terms associated with sensors and some loads: ‘NPN’ and ‘PNP’. You must understand the relationship between the field device and the control module in order to choose and install components properly when needed.
