How much voltage we get between two wire of 4 to 20 ma output? Is this voltage up or down respectv..

Answer / kiran

normally you gets 24-30VDC diretly connecting the volt
multimeter acroos it.

Also depends on the connecting the load resistance across
it.

E,g. When you are connected the 250 ohm load across it then
you get 1-5 volt or for 500 ohm 1-10 volt up & dowm
respective 4-20mA.

Answer / srinivasansureshkumar

yes, it is.
Better to verify transmitter power Vs load Graph.(TX
manufacturer Manual)
you will understand a lot about the question related then
just understanding the 4~20 ma in normal condition.

Answer / ajay ugale

if we r using 250ohm resistor in parallel with the signal
we will get 1-5Volt DC i.e at 4ma we will get 1 volt and at
20 ma we will get 5 Volt.

Answer / sathish kumar

It depends on the resistor. For 4-20mA o/p 200ohm resistor
wants to use. For 4mA o/p is 0.8V and 20mA o/p is 4V. It it
exceeds 4.4V means it will be short cicuit. To avoid these
problem zener diode will be use across the resistor for to
protect the system.

Answer / sagar

Between two wire of 4 to 20ma signal always we get 24 valts...there will minor change in it during 4 to 20
ma variation..

Answer / mail2noor.hyd

voltage is 0-10V

transmitter i/p supply (source) -24V
o/p -4-20mA/0-10V
we prefeered always current i.e 4-20mA,
b coz voltage travel a long
distance voltage will drop, so thats y we preffered
current i.e 4-20mA

voltage is 0-10V
