The IFM VKV021 is NOT a 2-wire, loop powered field device, it is a 3-wire device with an active output, so it will not work with this AI module. See page 4 https://media.ifm.com/CIP/mediadelivery/asset/5120ef5d2ab817439ce29db36e075ee1/704575_EN.pdf?contentdisposition=inline When Siemens uses the term "2 Wire" it means that the analog input module supplies 24Vdc (+) on the M+ terminal. The 24Vdc powers the field instrument, which is a 2-wire, loop powered field device. The connections for the AI dropping resistor and return to the power supply are made internally in the module and can't be accessed from the terminal block. |

Hello Thanks for your feedback! Which model of Siemens Analog IN will be suitable for this sensor? Can I use 6ES7 134-4GB11-0AB0, I have it as spare part. Thanks! Risto
