Single-loop controllers offer improved connectivity and enhanced features

The new Yokogawa YS1000 Series is a new range of single-loop controllers which offer improved connectivity with supervisory control systems and incorporate new, enhanced features that help operators work more efficiently.

Single-loop controllers are control systems that integrate an operation unit into a control unit and perform process control operations such as temperature compensation and pressure compensation for a specific control loop consisting of a sensor, transmitter, controller and operator terminal that carry out the production control process in sequence. They are widely used as backups in distributed control systems for large processes and in the control of boilers and other utilities.

Development background
To improve profitability, the petroleum, chemical and other process industries must maintain or increase the operation rates for their production processes as well as plant utilities, and reduce the costs of plant operation and system construction. The control systems for these facilities must not only be highly reliable but must also help to increase engineering efficiency and facilitate the work of plant operators.

Yokogawa’s established YS80/100 Series single-loop controllers are also highly reliable and have been selling well for use in distributed control system backup and utility control. Yokogawa has now added the YS1000 series to this product lineup to address user needs for better connectivity with supervisory control systems and improved access to process information.

Product features
While its predecessors used Yokogawa’s own communication protocol for connection with PCs and supervisory control systems, the YS1000 Series can be used with general-purpose communication protocols such as Ethernet and Modbus, adding flexibility to system construction.

The YS1000’s new colour LCD can display a message informing the plant operator that an alarm has been triggered. The improved visual display of such information helps operators to reduce errors.

The YS1000 has a depth of 25 cm, 7 cm less than the preceding model, and weighs just 1.6 kg, lighter than the previous model. This allows a smaller control board, thereby decreasing the cost of system construction.

Major target markets include the operation and control of production and utilities in the petroleum, petrochemicals, chemicals, and other process industries

The YS1000 series will be released for sale in January 2007.
