Why we using 4-20mA Signal instead of 0-20mA or 1-5V DC in Industrial Electrical & Automation

[@PLAYWITHPHYSICS-s9l]

Very very great explanation

[@abhishekkumargupta7492]

Nicely explained. I have one doubt. Can you please explain how input output cards convert signals and send to controller. I mean inside circuitry of io cards

[@rizwanqureshi9401]

Excellent explain

[@ElectricalAndautomation_guru]

Glad it was helpful!

[@jaysondkar5368]

Sir hum flow transmitter ko control valve kay badd may ku lagatye hai?

[@ElectricalAndautomation_guru]

so that correction is done by control valve can be seen in coming time .

[@jaysondkar5368]

@@ElectricalAndautomation_guru thank you sir

[@chandankumarpatra6725]

PLC jo 1 to 5 volt read karta hai wo kese karta hai

[@ElectricalAndautomation_guru]

it will automatically done by the card

[@jaysondkar5368]

Sir card ketnye volt par kam karta hai maine suna tha ki card jo 4-20ma ko 1-5 volt may convert kartha hai to card 1-5 volt kam kartha hai aysa maine suna tha.

[@ElectricalAndautomation_guru]

You are absolutely right.

Sir pull cord zss and belt switch ke bare me video banayeeee

[@ElectricalAndautomation_guru]

Ok, sure.

[@bhagyodayghadge5540]

Please explain digital input barrier wiring and working

[@ElectricalAndautomation_guru]

Ok.

[@mohammadpathan4668]

Well explained !

Thanks, please share with others

[@dhananjaymahakud4745]

Nicely explained...my question is why we use 4-20 , why not 3-19 or 5-21 mA ?

[@ElectricalAndautomation_guru]

It's because a 250ohm resistor is used to convert 1 to 5V output

[@Gurpreetkaur-qw1ff]

@@ElectricalAndautomation_guru Very informative sir!!!y 250 ohm resistor only sir??Why not some other value then.

[@ElectricalAndautomation_guru]

It will change the voltage value and will nit read by io card then.

[@Ali_SRC279]

Firstly:- to tern on the transmitter Second:- To distinguish the error in the event of a cut in the wires or the transmitter does not work

Sir make the video of three element loop

[@ElectricalAndautomation_guru]

Already present in list

Sir thoda easy way m btaye ki 4 to 20 he kyu krte h plzz
