The Wall Station is a compact, wall-mounted operator interface system that is ideal for process areas and plant floors where space is at a premium. In order to maximize floor space, the Wall Station attaches directly to the wall using external tabs or through holes located in the rear of the enclosure, making installation easy and straightforward. The Wall Station is available in a variety of configurations, including an inset keyboard style that minimizes the protrusion into the room, and a wedge keyboard style that is more ergonomically suited for periods of extended use. The Wall Station can be configured with a sloped top to eliminate the pooling of liquids on top of the enclosure, and can be optimized for liquid (washdown) or dry powder (wipedown) process areas. Additional options include precision cut-outs for push buttons, integration of additional peripherals such as bar code scanners, and a comprehensive selection of cooling options for extreme environmental conditions.
