INTRODUCTION:
The Sigma Myriad ‘ROS’ (Remote Operator Station) is a microprocessor based, state of the art, Remote
Operator Station for remote monitoring of variable speed drives, control valves or similar control devices.
The ROS is used with a primary measuring device whose output signal is compatible with common
analog outputs 4/20MA, 0-5VDC, 1-5VDC, and 0-10VDC.
Speed or process information is displayed in numeric format on the ROS’s graphic LCD display along
with the current value of the analog output.
All aspects of the unit are user configurable through the ‘plain English’ menus and combinations of the
5 user data key push buttons.
Available in 2 styles of mounting, ¼ DIN (4” x 4” nominal) and wall mounted Nema 4X enclosures, the
Myriad ROS is suitable for installation in all industrial environments.
