Hi,
I am trying to understand a 3-way valve and get confused by the following information.
- A normally closed valve has ports A, P, and R. When de-energized, outlet A is vented.
- A normally open valve has ports B, P, and R. When de-energized, outlet B is pressurized.
Could someone explain...
Could someone help me with this? I have a pressure transducer that outputs 30 mV max. How can I connect it to an AB PLC input card set up for 0 - 5V?
Thanks in advance.
