Pepperl+Fuchs introduces Division 2 KVM extenders. Consisting of a small transmitter and receiver unit, KVM extenders allow computers and servers to be positioned in a single centralized location away from any environmental hazards, while enabling users to send keyboard, video and touchscreen or mouse signals over distances up to 1,300 ft. (400 m). KVM extenders act as an electronic extension cord that enables users to keep their PC hardware in a safe area, while sending signals to remote hazardous areas. The affordability of desktop PCs, with their speed and enhanced graphics, provide plant operators with greater control and higher performance for less capital than PLC-based control interfaces, the company says. Additionally, having an operator workstation on the plant floor reduces inefficiencies and helps operators make informed process or control decisions. It can also help reduce operator confusion by providing one common HMI view. KVM extenders require no setup, configuration or special software to operate. They are available in three versions to satisfy varied application needs, including VGA to Cat 5, DVI to Cat 5 and DVI to fibre optic.
