PT100 v/s Thermocouple

2rlp · Oct 9, 2006

Hi everybody,
My client wants his proccess temperature to be monitored & so I installed an Unitronics M91 PLC with an add on I/O Module (IO - ATC8). In the help section there is a mention of PT100, whereas in the I/O configuration section, only Thermocouples, Analog voltage / current inputs are mentioned, no way of choosing a RTD, (PT100 has been provided by the client). How do I solve this problem without changing the hardware?

Thanks in advance

Ron
