Description
The MS5 Control Unit is a mechanical switching module used in AUMA actuator systems to monitor and control valve end positions and overload conditions. It integrates limit switches and torque switches in a compact mechanical assembly, providing reliable feedback and protection for actuator operation without electronic signal processing.
The MS5 unit ensures safe valve operation by switching off the actuator when end positions (OPEN/CLOSE) or preset torque limits are reached.
