Rugged, mid-size monitors that can be used as front-office PCs or in hazardous
areas. The display is an ideal NEMA 4X solution for HMI.
Slim and Economical
With its moderate weight and small footprint, the VT900ES series is ideal for
applications where both space and budget are limited.
Durable
The VT900ES monitors is fully enclosed in sealed, NEMA 4x, easy-open,
stainless steel cases. The chassis has no external vents, so nothing can get
under its skin, including weather, dust, dirt, moisture, oil, chemicals or other
harsh contaminants. A hard-anodized cast aluminum heat exchanger and
internal heat management system keep it cool in environments where ambient
temperatures approach 50°C/122°F -- without using outside air.
With its lightweight yet rugged construction, and either precabled or bulkhead
connectors, the VT900ES display is easily mounted on walls, stands, arms or
other industrial equipment.
The display is available with optional brackets, that conforms to VESA flat panel
mounting standards.

_____________________________________________________________

Purge System w/ Pressure Switch (Class 1, Div 2 Protection)

Enclosure pressurization or purging system that operates on a supply of
compressed instrument air or inert gas. It regulates and monitors pressure
within sealed (protected) enclosure(s), in order to prevent combustible
dust accumulation or remove and prevent flammable gas or vapor
accumulations. The system accomplishes four air exchanges and maintains
a "safe" (0.25") pressure. These processes reduce the hazardous
(classified) area rating within the enclosure(s), in accordance with the NEC
- NFPA 70, Article 500, NFPA 496 and ISA 12.4.

OPERATION

In accordance with system instructions, start-up requires air supply to be engaged
and enclosure power to be deenergized. In Class I areas, the user must perform an
exchange cycle (determined by the safe pressure flow rate—five minutes minimum)
before power can be energized. Loss of safe pressure requires immediate attention, unless power is deenergized. The purge system includes an explosion proof differential pressure switch with form "C" contacts for audible of visual alarm
systems.
