Product Advantages 

 RS485 digital communication signal output, the digital output signal 

has multi-turn value and single-turn absolute value. 

 Adopt standard ModBus-RTU communication protocol, support 

Kingview, Intouch, FIX, synall and other popular software, and can 
realize data communication with equipment and systems of 

international famous brands such as AB, Siemens, Schneider, and GE. 

 Full-scale true multi-turn encoder composed of precision reduction 

gears, no battery needed, power-off memory; any position within the 
range is unique, even if there is interference or power-off movement, 

the number of turns will not be lost . 

 A simple multi-turn encoder with a single code disc + precision 

reduction gear, multi-turns are 0-99 turns, single-turns are 0-
32768P/R absolute values, and a resolution of 0.35 degrees can be 

achieved within the range. 

 All parameters can be set through the RS485 communication of the 

computer, and the zero point can be set at any position. Therefore, 
when the encoder is installed, the device can be left at any position, 
and the connecting shaft can be fixed without considering the rotation 
position of the encoder. After power-on, it can be automatically 
corrected by performing a zero-setting operation at the external lead 

or through RS485 communication. 

 Especially suitable for reliable/accurate measurement of the height, 

stroke, angle and speed of tower cranes, mine cranes and 
construction hoists.
