Did you have dream to powering up your own vehicles by hydrogen power? These clean power will give you the best fuel for your own vehicles and environment. By using hydrogen to perform your daily activities, you have contribute to make this world become confortable for your next generation. On these article I will provide model list, price, and short explanation for several brands hydrogen generator that very suitable for your applications.
PH Series
These series employ a platinum catalyst in the anode electrode area which recombines any stray oxygen before it can contaminate the hydrogen stream. The involving of platinum catalyst is the best method to get high purity of hydrogen production (>99.9995% consistent purity). The generators require only distilled water (example : sea-water destilation) or de-mineralized water and electricity to operate, making these systems safe and easy to maintain. The Hydrogen Generators feature sophisticated control and dual redundancy safety systems, with LED status indicators and audible alarms with automatic shutdown. Complies with all current OSHA and European regulations. Please contact QUADREX CORPORATION for more detail information. Continue Reading »

Base on my short experiences when execute several automation project, I would like share how to make the instrumentation wiring diagram. The main concept that needed to be understand when make instrumentation wiring diagram is we should ensure there is no noise that disturb the signal from field transmitter and to field actuator. Control loop’s actual performance of automation system will affected when signal transmission from/to actual field instruments are disturbed by noises. Several sources of noise that needed to be considering are:
- High AC Voltage Cable → when instrument cables adjacent to strong AC fields which are present near large motors, generators, electric furnaces, and transformers, then instrument cables will act as an antenna that picking up the magnetically noise that generated by that devices.
- Radio Frequency (RF) radiation → these noise generate by walkie-talkie signal interference near to instrument cables.
- Electrostatic or capacitive coupling with other circuits system.
- Direct coupling with other circuits system, like leakage current paths, ground current loops, or a common return lead for more than one circuit system. Continue Reading »

ADAM-5510KW/TCP is PAC (Programmable Automation Controller) base on IEC-61131-3 standard package. IEC-61131-3 is the third part of open international standard IEC 61131 for graphical and textual PAC programming languages. Base on IEC-61131-3, PAC should support these programming languages :
- Ladder Diagram (LD)
- Function Block Diagram (FBD)
- Structured Text (ST)
- Instruction List (IL)
- Sequential Function Chart (SFC)

On this chapter I will show you how to configure Wonderware ArchestrA 3.0 to control and monitor 2 or more PLC SLC500 via TCP protocol. Before that, you should have already install :
- Microsoft XP Professional Service Pack 2 – minimum operating system
- Microsoft SQL Server 2005 Service Pack 2 – repository database when running ArchestrA application
- Wonderware Intouch 10 – main template to insert ArchestrA symbol libraries
