Technical Data
Operating Principle
Enclosures & Mountings

16 function keys, 8 softkeys and 23 alphanumeric and system keys make the ET-125-B the most multi-functional operator interface among the FALCON series – a basic device in plastic enclosure. Designed for machine-level operations, the ET-125-B is ideally suited for applications in different production areas, onboard ships and in tank farms – certified for hazardous areas, Zone 1, and suitable for use at temperatures ranging from -20 °C up to +70 °C [-4 °F up to +158 °F].

The transflective, 114 x 64 mm (4.5 x 2.5") LCD monochrome display with LED backlighting ensures optimal readability both indoors and outdoors.

The device comes in a rugged plastic enclosure; display and keyboard meet the IP65 standard: they are covered with polyester film that protects against dirt, dust and aggressive atmospheres. The operator interface is available either as a front-mounted control panel, or, optionally, can be mounted into plastic or stainless steel enclosures.
The complete display module is available as a control panel module, and can be mounted in both plastic or stainless steel enclosures.

The ET-125-B operator interfaces communicate with PLC over a number of different protocols: serial / MPI / Profibus DP (more options available upon request) – the SPSPlusWIN software allows fast and cost-effective project engineering.

The range of accessories includes intrinsically safe Mifare card readers, Ex-i barcode scanners, field and connection cables, handling blocks, and the SPSPlusWIN software.
The ET-125-B is also available as a complete package, including power supply, transmission unit and cabling.
