OVERVIEW
The MTL GECMA 19, 22 and 24 WS display modules are high-resolution graphical
panels specifically designed for use in hazardous areas. They are designed to be
accompanied by other MTL GECMA modules that will normally consist of, at least,
a power supply and a communications (COMs) module – both of which must be
designed for use in the hazardous area.
Other peripherals such as a keyboard and one, or more, pointing devices (e.g. mouse,
trackball, touch pad, joystick) normally accompany a display in the hazardous area, but
these may be omitted if a “touch-screen” option has been chosen.
Video data must be supplied locally from the COMs unit which in turn receives the
digital video interface (DVI) signal from a PC in the safe area or local COMs unit
dependent on which COMs version is being used.
A MTL GECMA WS display module MUST be powered from a MTL GECMA WS
power supply (PSU) to maintain its certification status. Two PSU models are available,
which enable the supply to come from either a 100-230V AC or an 18-36V DC source.
