Hi All From time to time i need to apply a 4 - 20mA signal to a circuit replacing the 300 Bar. Pressure Xducer for fault finding reasons. where can i got a kit or diagram for a current source i can build myself. |

What have you tried? |

Wait a minute. I thought the controller supplies the power and the transducer is powered by the controller and varies the loop current between 4 and 20 mA. So what do you want to do? A transducer simulator which will vary the loop current so you can test a controller? Or a controller simulator which will provide power to test transducers? Or is it that you are trying to simulate transducers which have their own power supply and power is not supplied by the controller? Or am I not understanding the question? |

Or NSI50010YT1G Doesnt get easier than this. |
