Relay on Eurotherm3400 controlling issue

Relay on Eurotherm3400 controlling issue

‎01-12-2023 05:24 PM

Hello Everyone,

 

I need assistance in developing a LabVIEW program to operate an OP3 Relay Module of an EPC3004 for automatic heating/cooling changeover applications.

 

I have an experimental room fitted with a glycol system with a heating and cooling circuit. The EPC is supposed to control a valve that feeds the glycol system with heat/cool water depending on the test demand. iTools works fine, I just change the value of the output from 1.00 to 0.00, and the valve opens. But I am a bit confused about controlling the output OP3 in LabVIEW.

 

Can someone help? Thank you!

 

Valerie
