The ATB-1 Trackball (and IBTB-1 interface) is an ideal input device for mining environments.
As an alternative to Intrinsically Safe (IS) keyboards, the system provides a reliable, low maintenance solution for user input into hazardous area equipment.
Located within a small IP54 metallic enclosure, the Trackball can be mounted to the outside face of a range of machinery, including DCBs, control and monitoring units, pump stations, substations or any other piece of equipment where a SCADA system is in use.
Features include:
The Trackball has been used and proven to be a reliable input device in the United Kingdom and has recently gained certification for use in Australia.
The ATB-I Trackball connects to the non-IS circuits through a Trackball Interface IBTB-1 situated in a safe area or within a separately certified flameproof enclosure. The ATB-1 Trackball module is provided with an integral cable which is to be terminated at an Ex d Bush, Ex d connector or through an Ex d cable gland mounted in the wall of the flameproof enclosure. The unit comprises a Trackball with three sealed push switches, mounted within a metallic enclosure with a degree of protection of at least IP54. The electronic components are mounted on four printed circuit boards supported within an inner transparent plastic framework and are provided with a degree of protection of at least IP54. Movement of the trackball is encoded via optical readers which view the trackball through the transparent inner housing. The ATB-1 Trackball is suitable for operation within an ambient temperature range of -20°C to +40°C.
