Burnout test for Yokogawa transmitters

2018-06-20View Original

Thread Content

Is there anyone who knows about the burnout testing of Yokogawa transmitters? How is testing carried out during circuit testing? According to the owner’s specifications, it is required to verify that the burnout direction is set in accordance with the data sheets. Simulate a burnout condition by applying equivalent NAMUR-compliant analogue output values for either ‘fail high’ or ‘fail low’, and then verify the corresponding failure response (display values, indications, controller actions) within the system. Those who are familiar with this process please let me know; thank you very much~
