HI,

i am using ml 1500 ALLEN BRADLEY WHICH IS USED FOR BURNER MANAGEMENT CONTROL, I AM RECEVING 02 NOS OF ANALOG INPUT (FLOW TRANSMITTER 4-20 MA , COMBUSTION AIR FLOW AND NATURAL GAS FLOW)
AND MY FINAL CONTROL ELEMENT IS FLOW CONTROL VALVE AND COMBUSTION AIR DAMPER , WHICH IS USED TO CONTROL AIR FUEL RATIO

PLZ SUGGEST ME AS TO WHICH OUTPUT CARD SHOULD BE SELECTED IF I WANTED BOTH ANALOG INPUT AND OUTPUT IN SEPERATE CARDS

Analog input - 1769-IF4 This is current or voltage input

Analog output - 1769-OF2 This is current or voltage output.
