Posted 11 Jun 2015 Good Afternoon everyone. I am a new user to MrPLC but a frequent visitor. Previously I have managed to find answers to my questions without having to register. My question today involves an Analog Output Card 1746-NO4V. I have installed the same project on 2 separate machines and get the same result on both?? I have a SLC 504, I am using a Schneider XDAL11131 Analog Joystick, feeding into a 1746-NI4 Analog Input Card. I get a full signal from the Joystick. -32767 and 32767. I take this signal and using a couple of SCP's I output to a 1746-NO4V Analog Output card. Again I output a full signal of -32767 and 32767. I was expecting an Output Voltage of +/- 10 Volts but I am only getting +/- 6 volts. I am supplying a Vickers Proportional Valve. How can I achieve +/- 10 volts? Thanks in advance Barry Share this post Link to post Share on other sites
Posted 11 Jun 2015 (edited) Are you powering the module from the backplane or external power? If from the backplane you might try from an external power supply. powersource.pdf Edited 11 Jun 2015 by Mickey Share this post Link to post Share on other sites
