Ronan Systems Model X120 Multiplexer is designed to continuously monitor up to 48 dry field contacts, voltage transition (live contacts), or solid state switching devices (SCRs, transistors, etc.). All inputs are converted into serial communication and then transferred to a receiver such as a Digital Control System (DCS), Plant Computer, or Serial Input Device like the Ronan Systems Model X110 Visual Annunciator Controller.

  • Significant savings in cable cost by use of serial transmission
  • Self-test, watchdog timer and loss of power relays
  • Integral ground fault detector
  • Single or redundant power supplies
