ABB LDGRB-01 3BSE013177R1 Gray Encoder Board
Description: 
The LDGRB-01 is a Gray-coded absolute encoder interface, used for fast and accurate measurement of the absolute position of a rotorvia a position encoder terminal.
The communication with the encoding terminal is done over a 24V electrical interface. This interface can be either parallel or serial. The LDGRB-01 canalso deliver analog signals to a speed monitoring instrument and a pulse encoder.
The communication with the controller platform AMC-33 is done over an optical DDCS interface with one sender (Tx) and onereceiver (Rx).
A frequently used example of an application for the Grey encoderiswhen it is connected between a SCYC 55830 (Tachoterminal board)and an AMC-3 (Application & Motor control board).In some applications also NTAC (Pulse encoder interface) isconnected to pulse outputs.
