U-ONE® system: Absolute encoder module

The universal encoder system U-ONE from Johannes Huebner Giessen offers ten function modules in a single unit. The absolute encoder module is available for interfaces such as CAN bus and PROFIBUS; a multiturn version is also available with SSI and Ethernet interfaces. The programmable parameters are based on the counting direction, the preset value as well as the lower and upper limit switch functionality.

Other function modules belonging to the U-ONE system offer the following functions: Position detection, electronic overspeed switch including programmable switching speeds from 0.63 rpm, various bus interfaces, diverse Ethernet connections, electronic cam controller, synchronization module and graphic display of sequential processes.
