Computerterminal (RT) Ex in Zone 1/21 und 2/22 von MTL GECMA

The MTL GECMA Work Station range has been designed to address the environmental challenges of obtaining visualisation within harsh and hazardous areas. Building upon decades of experience and expertise and the significantly large installed base of its predecessor, the MTL GECMA Work Station is packed full of features and state-of-the-art technology. The range includes Remote Terminal (RT), Thin Client (TC) and Personal Computer (PC) to meet a wide variety of applications. Suitable for the strictest of hygienic conditions and aggressive production environments, its slim, flexible modular construction also includes individually certified modules to allow safe maintenance even in hazardous areas.

Unique modular design concept - key features

The MTL GECMA RT provides a user-friendly, near real-time ‘plug and play’ solution that enables a safe area PC or Thin Client to be remotely controlled from the hazardous area, via a single, point-to-point connection.
The MTL GECMA RT comprises of individually Ex certified, modular components from the MTL GECMA Work Station range, such as power supply, displays, keyboard, pointing device and mechanical hardware. The simple addition of a RT communication (COM) module is then added to deliver a Remote Terminal solution.
