The CTU is a rugged, wall mounted termination unit designed for installation alongside compatible Acoem instruments. Due to the diverse tunnel power and communication requirements, the CTU adopts a modular design philosophy. Enclosures and terminal packs are offered separately so customers can specify and purchase the precise configuration required for their application.

The CTU is available with and without an onboard power supply along with a range of terminal packs including sacrificial OVP terminals. Enclosures are manufactured from stainless steel which provide IP67 rated ingress protection. Enclosure lids benefit from quick release catches and a security lock screw to prevent unintended access.


  • Rugged design to withstand corrosive atmospheres and regular tunnel washing
  • Terminal packs are available separately allowing customers to buy the precise configuration to suit the application
  • The optional power supply can provide 24Vdc for up to two monitors
  • Din rail ready to accept terminals
