DataWorx with Do-more PLC support

DataWorx with Do-more PLC support

AutomationDirect has partnered with BizWareDirect for several years, supplying DataWorx data collection and monitoring software for compatible DirectLOGIC programmable logic controllers (PLCs), Productivity3000 and WinPLC controllers. Previously, it had been necessary to purchase an OPC/DDE server and write code, or buy an HMI package, to collect data from AutomationDirect controllers. BizWareDirect’s data collection software makes ... Read More

What to Know When Selecting an Enclosure

What to Know When Selecting an Enclosure

NEMA enclosures house all kinds of electrical components from simple terminal blocks, to industrial automation systems, to high voltage switchgear. In industrial automation systems, NEMA enclosures often house motor controls, drives, PLC/PC control systems, pushbuttons, and termination systems. Some enclosures are shaped to be operator consoles. AutomationDirect offers over 2,200 enclosure part numbers across NEMA ... Read More
 
Encoders Explained

Encoders Explained

What are encoders? An encoder (for industrial controls) is a special sensor that captures position information and relays that data to other devices. The position information can be read in many ways (optically, magnetically, capacitively, etc.). There are two basic geometries for encoders: linear and rotary. A linear encoder typically consists of a scale (a ... Read More
 
Important Considerations for Replacing and Sizing AC Motors

Important Considerations for Replacing and Sizing AC Motors

How to determine whether to rewind or replace a motor, and how to find the right motor size for your application. Every business is trying to conserve energy in the face of high utility costs, so getting the best return on investment (ROI) is critical for maintaining a healthy balance sheet. The decision to replace ... Read More
 
Electrical Arcs (Part 2 of a 2 Part Series)

Electrical Arcs (Part 2 of a 2 Part Series)

In Part One of this article we discussed the equipment and procedures used to manage the damaging effects of arcs in electrical equipment. In Part Two, we will discuss some of the basic methods, tools, components and circuits that should be used to operate safely around circuits with high arc potential. Part One can be ... Read More
 
Electrical Arcs (Part 1 of a 2 Part Series)

Electrical Arcs (Part 1 of a 2 Part Series)

Those of us who have worked with, or around, electrical equipment have witnessed electrical arcs. At the very least, we’ve seen the sparks produced when a relay or contactor switches off. Similarly, most of us also know that repetitive arcing can be very damaging to contacts over the long term, requiring periodic replacement of relays ... Read More
 
Why is my TVSS an SPD?

Why is my TVSS an SPD?

In the last few years, the electrical industry has seen significant changes in safety standards. One area of major change is with surge protection. In the past, you would use a surge arrestor or transient voltage surge suppressor (TVSS) to solve transient overvoltage or surge issues. Today, we don’t even use the words surge arrestors ...

NEMA or IEC Standards?

NEMA or IEC Standards?

Those of us who have worked professionally in the U.S. electrical control industries have a good understanding of, and a certain level of comfort with, NEMA standards; most notably as they pertain to electric motors, motor controllers and enclosures. For the most part, American-based companies require that the electrical components and enclosures used in any ... Read More
 
Transformers: Application, Construction and Efficiencies

Transformers: Application, Construction and Efficiencies

Part One of a Two-Part Series Although most of us have encountered transformers in our professional lives, it’s surprising just how little the average designer or technician knows about them. A transformer’s principal function is to “transform” alternating current from an undesirable voltage to a voltage that is appropriate for the circuit at hand. A ... Read More
