hi friends,
i' m new to plc world and i was connecting a k type thermocouple to PID to get 4-20 mA output to connect it with plc analog card.but after connected i was getting values of signal output when i have achieved the set value e.g 500 deg celsius then it should show 20 mA and when temp is lower than that 500 deg then it should show lesser than 20 mA but its not varying linearly.can anyone help me out of this mess....????thankyou in advance.....
PID input is K-type thermocouple output in mV and i have used a Delta PID of current output(4-20mA)to get it connected with Omron CJ1M cpu11 plc.Please Reply its very urgent my mail id is [email protected]
