Rotator Controller Module for

RK3 Antenna System Controller

General description MK is universal motor control module for controlling one rotator. MK module provides 12/24VDC or 12/24VAC (for current ratings please see table below). MK module occupies one hardware slot out of eight in RK3 mainframe. Module consists of software controllable power selection unit and control unit, which controls power output, disconnects the output in case of over current and senses the position of rotator by potentiometer or rotary encoder.

MK module diagram Position of rotator can be sensed in two different ways. First one is with potentiometer integrated in rotator, the second one is with rotary encoder. When using rotary encoder, you can choose absolute or incremental encoders. You can also choose interface type i.e. single-ended or differential RS422.
