The EIM Multiport Actuator (MPA) is an electronic system specifically designed to control and monitor the operation of the Multiport Flow Selector. It combines an exclusive solid state motor starter with control software to provide precise positioning of the Multiport Flow Selector within +/- one degree of the selected port, retaining that position even in the event of a power loss. The MPA provides configurable port selection from 3 to 8 ports.  The MPA allows user to select any port as home port or skip any unused ports.  This actuator allows for field torque adjustment while protecting the Multiport Flow Selector from excessive torque. The MPA stores alarm history to detect abnormal operating conditions for preventative maintenance of the MPFS and the MPA.

The Multiport Actuator interfaces with industry standard network communication protocols. The MPA is designed to operating in harsh and hazarious environments.  The MPA provides manual override upon loss of power. The actuator is capable of working with a wide range of voltages - three-phase, single-phase and DC.
