  • Any Combination of Channels May be Simultaneously Selected
  • High Quality Reed Switch Contacts for Reliable Switching with Long Life
  • Very High Insulation Resistance


20-330 high voltage multiplexer modules will switch up to 2kV with 3kV isolation. They provide low cost, high voltage multiplexing with up to 192 channels per mainframe, expandable to over 1000. Each module may be configured as either a single 48 channel or dual 24 channel multiplexer. Programmable as a conventional break-before-make multiplexer or in multi- channel mode where any combination of channels may be selected at the same time, very useful in cable leakage testing applications. These units are designed for both “hot ” switching (close switch after load applied) and “cold ” switching (close switch before EHT load applied) high voltage applications, giving very reliable switching with no disruption to internal logic. For large multiplexer systems automatic isolation switching connects only those multiplexer banks which contain active channels ,this maximises performance in large multiplexer systems
