ROC800-Series Remote Operations Controllers

The ROC800-Series has become an industry leader for a variety of remote automation applications. As a Remote Terminal Unit (RTU), the ROC800 has built a strong reputation as a rugged workhorse with great flexibility. The series consists of the ROC809 and the ROC827.

The ROC809 has a backplane that supports the central processing unit (CPU) module, power input module, three communication modules, and six I⁄O modules.

The base ROC827 has a backplane that supports the central processing unit (CPU) module, a power input module, and up to three communication or input⁄output (I⁄O) modules. You can expand the ROC827 by adding up to four expansion I⁄O racks. Each expansion I⁄O rack has a backplane and six slots to house I⁄O modules. The three modules of the ROC827—when combined with a maximum of four expansion I⁄O racks—allow expansion up to 27 slots.

ROC800L Remote Operations Controller

The ROC800L is programmed to measure and control the flow of liquid hydrocarbons. These liquids include Crude Oil (API Group A), Refined products (API group B), Specialty Products (API Group C), Lubricating Oils (API Group D) and Light Hydrocarbons (API Group E). Other products can also be measured when physical characteristics such as density and thermal coefficient of expansion are known.

The ROC800L is ideal for oil well testing, Net Oil Computations (NOC), Leased Asset Custody Transfer skids and many other applications in oil production at the wellhead. It is also at home in pipeline control and custody transfer (fiscal measurement) applications and leak detection, and other pipeline transmission applications.

The ROC800L comes from the factory with programs installed and can be set up for most operations in minutes using ROCLINK configuration software.

For special control tasks the customer may add simple Function Sequence Tables (FSTS) for programming or with the DS800 tool program in any of the five EIC programming languages.
