Local Actuator Control
Local Actuator Control

The Rotork Local Hand Station is suitable for applications such as large penstocks, where it is difficult to access the actuator due to height, in chamber applications where the actuator is located below the ground and space is limited or for control when the actuator/device may be in a hazardous location. The Local Hand Station provides a simple control panel interface between the actuator or field device and the Distributed Control System (DCS). The Local Hand Station offers complete local override of DCS control signals to ensure localised maintenance activities can be performed safely without unexpected operation occurring.

No need for supplementary power supplies

Absolute control is critical to site safety so in addition to an Emergency Shutdown (ESD) button, the rotary selector switches have been used due to their increased resistance to sticking or jamming and the Local/Stop/Remote selector can be locked in any position. The Local Hand Station can be pole or wall mounted and is ATEX and IECEx certified. Power can be supplied directly from the connected actuator, meaning that installation can be carried out with just a standard electrical cable. This prevents the need for any supplementary power supplies on site.
