Hi everyone I want to acquire some temperature measurements from thermocouple units, monitor and project them on a monitor. Number of thermocouples are about 40 and they are K type. The distance between thermocpules and PLC is more than 20 meters. 1. [snip] ... 2. Should I use temperature transmitter with 4-20 mA output and use analogue cards (6ES7331-7NF00-0AB0) or use thermocouple cards (6ES7331-7PF11-0AB0)? What are differences? Thank you in advance ------------- |
