MTL4000 Series isolators
 Isolating IS interfaces

Connecting control systems for hazardous process plant can be as straightforward as connecting them to plant in safe areas when using the MTL4000 series backplane mounted isolating interfaces.

With over 1,000,000 units sold since its introduction, the MTL4000 series has been integrated into practically every application and has been adopted by all the major DCS suppliers including Honeywell, Emerson, Invensys, Siemens, Yokagowa and ABB.

  • Compact modular design
  • System backplanes with bussed power
  • High module/packing densities
  • Custom backplanes for closest integration
  • Reduced system engineering costs
