Hi to all.
My question: I would like to use the product in object, and in the datasheet ( about on input ) it is written that we have to use a current between the range 2-12 mA. So the correct resistance ( that is the value) is external ( depended on Vexternal) and we have to add. Correct? In the scheme ( https://www.industrialshields.com/shop/product/is-io220vac-5t24vdc-optoisolated-digital-input-module-converter-12vdc-vdc-to-220vac-to-5-24vdc-555?category=5#attr=) I don't see any mention on this.
