Dear Experts I'm using s7 1200 14c dc/dc/relay and i need to connect this sensors to it but the problem is that every sensor has a different voltage level and most of them less than 24 V so please can any one help me to solve this problem 1- light sensor (light detection) 2- humidity sensor 3- temperature sensor (water temperature) 4- co sensor 5- co2 sensor 6- water detection sensor 7- vibration detection sensor 8-motion detection sensor thank you in advance

https://support.industry.siemens.com/tf/ww/en/posts/di-module-signal-level/77707/?page=0&pageSize=10 says the digital input voltage level...if your sensor voltage level is less than the described level u ask for the supplier with 24v voltage output or use some 5v or 12v relay to switch to 24v... in your case i didint understand co and co2 ,in case of humidity u have to go with some amplifier since it is 5v and in case of pt100 u have to use s7 1200 RTD module which supports Pt100 ,water detector and vibration sensors are no contact so u can switch 24v in it...a |
