Erlich Industrial Development Corporation

High-end computerized lab equipment, accessories and sensors. They also manufacture OEM transducers, signal conditioners, industrial standards interface boards and kits. (USA Firm)

Erlich Industrial Development Corporation

Erlich Industrial Development Corporation (EID) is an OEM manufacturing and R&D Company specializing in the development of high technology biological, medical and chemical research products.

Adjustable Output Positive Voltage Power-Supply Kit

Interface board conductivity

An electronics board (kit) that allows you to connect up to 30V AC or DC on one side of the board and get adjustable VDC regulated on the other side. Every lab should have a few of these boards handy. The boards will allow you to easily power all your analog components (i.e. op-amp). The Terminal Block TB connector is included and makes it easy to use.

Interface board conductivity cell with DIN Rail clip

Interface board conductivity

Build your own Conductivity meter and/or controller and save. Simply connect your Conductivity cell (conductivity electrode, Probe) to the input via Terminal Board (TB) and the output to analog to digital converter (ADC), Digital voltmeter (DVM), Analog Voltmeter, micro-controller (MC) or PLC. Power the board and get reading.

Electronic Educational Applets - Paul Falstad

"These are some educational java applets I wrote to help visualize various concepts in math, physics, and engineering." - Paul Falstad (now with HTML5 and Canvas)

Electronic Educational Applets - Paul Falstad
  • Math and Physics Applets - MyPhysicsLab - Physics Simulation with Java.
  • Index of Circuit Examples - Demonstrates various electronic circuits.
  • Digital Filters - Filters digital signals and plays the output on your speakers.
  • Acoustic Interference Applet - Audio interference between your speakers.
  • Waveguide Modes Applet - Electromagnetic waves in a waveguide.
  • Antenna Applet - Generates antenna radiation patterns.
Electronic Educational Applets - Paul Falstad

Analog Circuit Simulator Applet - Demonstrates various electronic circuits.

"This java applet is an electronic circuit simulator.  When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage.  The gray color indicates ground.  A red color indicates negative voltage.  The moving yellow dots indicate current."

iCircuit is the easy to use electronic circuit simulator and designer - the perfect tool for students, hobbyists, and engineers.

Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.

Learn + Make + Teach Electronics at EveryCircuit

Build any circuit, tap play button, and watch dynamic voltage, current, and charge animations. This gives you insight into circuit operation like no equation does. While simulation is running, adjust circuit parameters with analog knob, and the circuit responds to your actions in real time.

NetSCADA - Scaleable SCADA and HMI

NetSCADA is an Enterprise Client/Server HMI and SCADA system that allows configuration and monitoring over the Internet. NetSCADA's object-oriented configuration allows users to easily organize and replicate multi-RTU sites in a fraction of the time a traditional SCADA / MMI would require.

NetSCADA - Scaleable SCADA and HMI

Internet SCADA or Web-based SCADA makes use of IP technology in SCADA and can range from IP tunnels over satellite, frame relay, fiber, radio to link SCADA networks to central office to individually IP addressed instruments or use IP enabled devices or web-based SCADA Host MMI Software such as NetSCADA:
