Hello! I am curious if RTD modules can also function as regular analog inputs. I am currently using an RTD module for RTD sensors, but I have some extra inputs available. I would like to know if these inputs can be utilized for other purposes as well. Thank you!
I am skeptical, as the PLC applies a voltage to the RTD (Resistance Temperature Detector) to gauge its resistance. While it is possible to measure other resistances within the RTD's range, introducing an external voltage or current to the input may disrupt the process.
While I may not be an electrical engineer, there might be a circuit solution that enables the RTD card to interpret a signal similar to a transducer. However, I have not come across one personally. The potential troubleshooting costs involved in creating such a circuit could outweigh the benefits, making it more cost-effective to simply purchase a new AI card.
Hey there! It really depends on the specific RTD module you’re using since some modules are designed strictly for RTD sensors, while others might allow for versatile analog inputs. If your module supports multiple input types, you could potentially use those extra inputs for other analog signals like thermocouples or even voltage outputs. It’s worth checking the datasheet or user manual for your module to see what’s specified. Happy experimenting!
