Eaton MTL GECMA HMI workstations

Eaton has expanded its range of MTL GECMA HMI workstations, introducing a thin client (TC) and personal computer (PC) version.

The TC and PC versions complement the existing MTL GECMA remote terminal (RT) and are approved to global hazardous certification for Zone 1 environments. As a result, they are suitable for use in hazardous EX zone areas in the chemical, pharmaceutical, refinery and oil and gas industries.

The TC version is designed for virtualisation applications, eg, for batch control. The workstation works with a client server in the safe room across a LAN. This saves space in the cabinet as users don’t need a dedicated PC and the user can control up to 255 HMIs from a single server.

The PC version is a stand-alone system and has system hardware that meets the needs of complex applications with high computing power demand. The workstation has a watchdog function that automatically monitors the operating system; if there is no input from the system, it automatically restarts itself.

RT is a point-to-point device, with one workstation assigned to one PC in the safe area, and features a keyboard, mouse and video. The RT terminal’s modularity means upgrades to existing installations are quick and easy, which can save time and minimise maintenance and downtime. Traditionally, the whole unit would have to be dismantled off site, but with MTL GECMA, individual parts can be replaced on-site, increasing plant availability.
