Answer Posted / parmar.ic@gmail,com
all types and levels are 4-20ma and 0-10mv v pule etc
because in industries somthing we assume in 0mA so the
control room is not understand outbut on the panel is not
display so any signal are come in panel and out put is
uderstand so 4ma any signal and it understand this procees
is any problem .so analo and digital I/O used in process
controle application are levels 4-20mA and 0-10v,mV
