Hi,
first my application is a galvanic isolated DAC with 4..20mA Ootput. I am using the adum1310 for the galvanic isolation of the Serial Interface of the loop powered AD421. I am using up to 6 of these couples parallel to transform digital data into…
Hi Leonfun, I am not sure I understand your comment but I will reply as best I can. First identify the hazards. If the hazard can then somehow be addressed using a circuit that looks something like a sensor+logic+actuator then you are talking about functional…
Hi,
I must protect my device. To do it i have used isolated DC/DC power source, and two ADuM1310. Problems occur when i should connect TVS to ground . I dont know which place is better, or im not sure in 100%. Isolated ground or field ground. I think…
IEC 61800-5-2 is an industrial standard which covers the functional safety of variable speed drives. In effect it tells you how to build a safe motor control circuit. In this blog I will discuss an example circuit found in Annex B of IEC 61800-5-2 to…
Hi Jelelnie
Thanks for your reply.
Unfortunately, I can't show you circuit diagrams as they will reveal sensitive company information, and I haven't got authority to do that.
What I can tell you is, that through a header with SPI signals and…
This technical brief compares methods of isolation in a traditional motor controller design. The Boston Engineering brief details the benefits of digital isolators compared to traditional optocouplers — which include reduction in cost, component count…
