If they are all connected together as it looks like they are, you won’t be able to select individual inputs – or are the address wires supposed to represent an address buss?

Board Setup and Configuration. It may ddatasheet the actual current. Of course, there is no way to measure the resistance of the other two leads because no significant current passes through them. Education equipment Industrial test tools Catalogues Laboratory measuring equipment Measuring of environmental and ambient parameters Equipment for testing of medical equipment Calibration equipment Soldering equipment Telecommunication measuring equipment.

Similar problem on the ; you can only select input from A0 or A2, unless the line to the uC represents a buss. An HC would be better at 5V. I am interested in developing a generic 8-channel cd40551 PT interface for RaspberryPi. CD maximum analog current Posted by washiloo in forum: The diode prevents the activation of other PT channels not if by HC Aug 7, 0. Calibration equipment Electrical calibration equipment Pressure calibration equipment Temperature calibration equipment.


Your name or email address: The customer is in the focus We want to make sure that customer is the center of attention. Add to cart On stock. Telecommunication measuring equipment Cable and pipe tracing Cooper networks IT networks Optical networks Spectrum analysers more But i could never find how they practically implemented this or if its performance suffered and so on. Do you have a data sheet? Post as a guest Name.

If the output is loaded down then the output voltage will be reduced. If you use the as a Demultiplexer you can choose between 8 different outputs and select just one you want to write at the time. No, create an account now. I am only now interested in 3-wire PT sensors as these are what available locally at affordable prices.

Please correct me if i’m wrong in this. Hello All, I am still facing the problem.

Additionally i need vatasheet wire compensation. Since it appears that the can support datawheet 1mA what you could do to avoid Ron influencing the measurement is using separate multiplexers, one to multiplex the current feed it to a sensor the other to sense the voltage. There is no such limit oc switch current- 1uA is leakage. The uC is working fine. Can anyone please suggest me how to deal with this issue? Hello All, Firstly, thanks a ton for the help.

Its been 2 months now I am having problem. Now, when I do not connect the amplifier, I do not see any offset voltage on it, however, the moment I connect the output of mux to it, the voltage at the input of the amplifier gets offset to around 1.


You can choose between 8 different inputs and select just one you want to read at the time.

Dec 20, 4. I already thank Bimpelrekkie and Spehro Pefhany for helping in such short period.

I am a novice mechanical eng. The tolerance of the resistors won’t affect the stability of the current from your current source. Instead i though i could make a differential measurement of voltage ix across the first two leads of the PT using A0 and A1 to get lead resistance.

I forgot to mention.

So the current may not be that constant. Bimpelrekkie thanks for clarifying. It is not possible to read or write more than one pin on the at the datsheet time, because you can only select one pin at a time. Sign up using Facebook. You can measure the ‘bottom’ lead resistance by measuring relative to ground. The output of 4: I could order online but it would take weeks and cost a lot import duties to india.

The will not work properly with its Enable-not pin floating. The current will always be 1 mA whatever value the resistor has.
