Basically I am looking for a device that will detect a rise in temperature within a specific time interval.
Our existing arrangement is a purpose built card with a K-type thermocouple input and a single on/ff input to the main PLC. This purpose built card is now becoming obsolete, hence the need for the new unit.
Obviously we could use a thermocouple card, read the real-time temp to the PLC and write a new block of programme around this. I want to avoid changes to the PLC programme, so a simple module unit would be ideal.
Are there any simple programmable units out there that could do this?
Appreciate any help.
