bobnorway Posted April 28, 2012 Report Share Posted April 28, 2012 Using Visilogic V9.4.0 running WINXP sp3 . V1040 with V200-18-E6B Re-installed visilogic software, updated operating system on V1040, created a new empty project, no change. The V1040 has a 24vdc supply. The problem is that the 4-20ma analog outputs (both channels) seem to be limited to about 10volts. This gives me a maximum loop resistance of 50ohms not the 500ohms stated in the manual. It would 'appear' that some software from a 0-10volt output is limiting the 4-20ma. Test it yourself: hang a 100ohm load and set the channel for 4095 decimal. This should work and give 20ma = 20volts but it doesn't, it'll stop at 11volts. Quote Link to comment Share on other sites More sharing options...
