  2. Controllogix 1756-OF8 Wiring help

    Hello everyone!  I am having some issues with the internal wiring/wiring of the 1756-OF8 analog output card in my Controllogix L55 controller. I have just recently started using  Allen bradley products, so please bear with me. If my memory serves me correctly, in my past experiences with other plc vendors I thought I was required to provide 24vdc+ from the power supply, which is common to all the channels used for driving the analog out(4-20ma) to the field device being controlled. But I can find any documentation from Allen Bradley that supports this. Can anyone shed some light on how to connect the power supply to the OF-8 card.   Thank you!! Shane
