spilleravr Posted February 26, 2016 Report Share Posted February 26, 2016 Hello, I got a V1040 with a V200-18-E5B expansion module. Is it okay to power the V1040 from a PC power supply using -12 and +12V connections to get 24V ? I did not find any info in the datasheet if negative voltage for POWER- is allowed. Anyone? Thanks in advance! Quote Link to comment Share on other sites More sharing options...
