As more info, the specs of the Redac are: Analog: 8 single ended or 4 differential channels 0 to +5 volts or -5 to +5 volts range Digital: Optically Isolated 5 to 24 volts DC Relay: 5 to 24 volts @ 1 amp current Hope this also helps Dan Carrington > Mark Sekelsky wrote: > > > > David, > > > > Thanks for the resistor lesson.
