Analog Mux for Data Acquisition Systems

Here is a 4-20 mA In/Out Analog Mux with Cascade option. This is a simple circuit i designed to make a Automation System within a budget.

Analog Mux using 4051

This takes 4-20mA from many Transmitters and gives out just one 4-20 mA output. The Mux is done with a digital byte or word.

 Industrial Process Control Circuits

This is a slow scanner as process is slow, that way many analog inputs can be multiplexed and sent into one analog input of a D/A. In near real time systems a faster mux could be used or mux totally avoided. This was made in some numbers, so the pcb is better than others.

Online Electrical and Electronics Books

Some books that will help you learn electronics and are free too. Youngsters have a great wealth to find in the libraries. The Present day has made more information available online, it supplements the library resource.

What can never be found in libraries are found on the net and can be searched too. Here every individual shares his projects, ideas and designs and is not edited or moderated by any publisher or media.

Navy Electricity and Electronics Training Series (NEETS)

These are nice Mini Reference Books that can build the Learning of EE students. Some interesting booklets - Circuit Protection, Control, and Measurement; Intro. to Wave-Generation and Wave-Shaping; Microelectronics and Test Equipment..

Navy Electricity and Electronics Training Series

Some of the Books on Embedded Systems and Communications are quite good and even the sample chapters will bring an appetite to study the subject and buy the Book.

United States Navy Electricity & Electronics Training Series - NEETS

The Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical and electronic related Navy ratings. Written by, and with the advice of, senior technicians in these ratings, this series provides beginners with fundamental electrical and electronic concepts through self-study. The presentation of this series is not oriented to any specific rating structure, but is divided into modules containing related information organized into traditional paths of instruction.

Multi Zone Temperature Controller System

This is a Multi Zone Temperature Control panel used in Plastic Extrusion Moulding. Building such panels helps us learn cable management techniques.

Multi Zone Temperature Controller

The panel is a standard way it was built and some of the merits were the selection of panel components and wiring expertise.

Electrical Control Panel Wiring

Just like rackmounts hold big instruments or computers, control panels small or big have to hold DIN Instruments, switches and annunciators to make it easy for the operator. The maintenance work also is simple from the backside. It can be kept near the machinery which it controls.
