I am currently using a Fisher 2500 Level controller in a contact tower. Independently I have a Rosemount 3051 DP Transmitter for level indication to the PLC. My Question??
Can I use the output of the Rosemount to power a Fisher 846 I to P to operate my control valve? Secondly, wiring the 846 from the 3051 would be parallel? Finally, will this disrupt the 4-20 mA output back to the PLC?
