Hi,
We have a very small project using PLC to control the pump to maintain a constant pressure for a water jet in a system.
There is an analog input from the pressure sensor (4-20mA) and output (4-20mA) is to a drive (to control the pump).
When the input from the pressure sensor is low, the pump must run faster to maintain the pressure. The pressure is fix and not adjustable.
Customer specified for either OMRON, Yokogawa or AB. Which ever cheapest. But I guess OMRON is the cheapest....but I'm not sure which model is suitable...can anyone please suggest.
No network or scara/touch screen.
