Introduction to Allen-Bradley PowerFlex Drives with Ethernet I/P

Introduction to Allen-Bradley PowerFlex Drives with Ethernet I/P

An overview of the Allen-Bradley PowerFlex variable frequency drive with Ethernet I/P protocol.


Using Sensors with Open Collector Outputs

Using Sensors with Open Collector Outputs

This article discusses how to use sensors with open collector outputs and learning some of the module connections involved.


The Purpose of NPN Sensors in Control Systems

The Purpose of NPN Sensors in Control Systems

A typical control system uses PNP sensors and tends to be easier to visualize. For opposite polarity systems, the NPN sensor is the only compatible sensor type. Learn more about NPN sensors, including characteristics and uses.


How to Reduce Electrical Noise on Sensors and Control Systems

How to Reduce Electrical Noise on Sensors and Control Systems

Electrical noise is a common problem inside industrial facilities. The following will explain a few simple strategies for reducing this noise.


How To Measure DC Voltage With a Multimeter

How To Measure DC Voltage With a Multimeter

The simplest and most common measurement to obtain using a multimeter is voltage, in fact, they are often called ‘voltmeters’ for this reason.

Using the Allen-Bradley Ramp/Soak Controller With a PID

This article will focus on using an Allen-Bradley ramp/soak controller with a PID.


How to Identify and Use NPN Sensors

How to Identify and Use NPN Sensors

In this article, we will discuss the application and identification of NPN sensors, clarifying why they work and how to properly use them in a control circuit setting.


A Guide to Identifying and Using PNP Sensors

A Guide to Identifying and Using PNP Sensors

Why do we need to use PNP sensors in certain applications, and which markings and diagrams allow us to identify these devices?


Using PID and Feedback Loops for Precise Motion Systems

Using PID and Feedback Loops for Precise Motion Systems

PID controllers are an excellent method of using feedback to turn an otherwise open-loop system into one which can follow a carefully prescribed profile, correcting for inconsistencies caused by the equipment, the environment, and even the products in the manufacturing process.


Connecting Remote Input and Output Devices Using Computer Networking Technologies

Connecting Remote Input and Output Devices Using Computer Networking Technologies

Networked remote I/O allows us to work with a machine center separately from the rest of the system, and drop the solution right in place.
