February 27, 2020 – Rotork’s Local Hand Station is an actuator control panel optimized to control actuators or field devices located in hazardous or inaccessible areas.
The 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.
Reliable local control is essential in many applications and the Local Hand Station provides a 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 localized maintenance activities can be performed safely without unexpected operation occurring.
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.
