Re: Intrinsic Safety
The term refers to an intrinsic property of material itself (the material substance). It is independent of the amount of material is present and is independent of the matter is in form (eg, a large room or a set of small parts). The intrinsic property are highly dependent on the chemical composition ...

Re: DCS - Distributed Control System????
It is usually better to have autonomy at any given point in case communication gets disrupted, the task then could carry on of its own accord. If you have a central control system, it either means a lot of high speed data communication in a probable electrically noisy enviroment, or in a simpler ...

Re: 4-20mA Vs Voltage Signals??
If I am right, CB-50 without a terminal component as resistance. analog input of the government has a high impedance much greater than the resistance you need a direct current voltage. Since the value of the proposed Kid 250E is normal. Mostly the area is 50-250 ohms. Energy source to drive at this ...
