I am wanting to use the 0-100 output data from a PID instruction to send out a 4-20mA signal from an analog ouput card to a Phase Angle controlled Solid State Relay. This is to control a heater. Using Logix 5000 L5563. I would like to know if I can just write a compute instruction to convert the 0-100 to a 4-20 and then write it to the analog out or is there a different way to do it. I know the analog cards are set up for either 0-10VDC or 0-20mA.
