Multiple valve actuator control solution

08 April 2019

Rotork has launched the latest generation of its monitoring and control system for valve actuators and plant equipment.

Suitable for use in all industries, the Rotork Master Station is said to be capable of operating up to 240 actuators across three separate field networks allowing the optimum network to be used in different plant areas. It now supports Modbus RTU protocol with third-party device integration and Pakscan Classic – Rotork’s standard two-wire loop system, which has more than 170,000 existing devices installed in networks around the world.

The Rotork Master Station includes many features designed to enable the management of the assets connected to it, for  condition monitoring or predictive maintenance purposes. 

Multiple host connectivity is included and the presence of multiple databases enables the Master Station to maximise data transfer efficiency. It can be supplied with built-in redundancy support via a hot standby configuration, allowing a replica unit to assume network control in the event of an error in the primary unit. All network communications are secured with fault tolerance, allowing for plant operation to continue, even if a fault occurs.

Installation is via a single twisted pair cable instead of more costly multicore cabling. The wired control loops can operate on long loop lengths up to 20km without external repeaters.
