We had an enquiry from a customer who needed a 4~20mA isolator – taking in a 4~20mA signal with excitation supply, and passing out an isolated 4~20mA loop, self, or auxiliary powered output, DIN rail mounted. The ADtek SD-PR matches this, but as with its two sister models in this slim 7.6mm series (SD-T and SD-CL), ADtek phased this one out as of June 2023.
This looks simple, but a phased-out model changes what we can promise. The SD-PR’s own spec is straightforward – 4~20mA input with excitation supply, and 4~20mA output that can be loop powered (self-powered) or externally auxiliary powered, in the same ultra-slim 7.6mm DIN rail housing, CE and RoHS certified. Since it’s no longer in production, any unit we source would be from remaining stock, and ADtek’s datasheet for this model is only published in Chinese.
In actual application, if you specifically need this exact isolator for a like-for-like replacement, we can check what stock is still available. If you’re open to it, ADtek’s current AT-series or AT2 slim converters cover the same isolation function with full manufacturer support and English documentation.
From our experience, before we quote this, we would normally check whether you need this specific phased-out model or are open to ADtek’s current equivalent, whether you need loop/self powered or auxiliary powered output, and confirm you’re comfortable working from a Chinese-language datasheet if we do source the original SD-PR. Hope this helps.
