1 830 Remote Terminal Unit Collect and transmit data from multiple storage tanks to a central system or host using a single tank gauge interface Benefits and Features Easily expandable through the use of plug-in interface modules - reduces cost by integrating all analog, digital and serial data inputs and outputs Multiple host ports - adapts to your needs and redundancy requirements Supports multiple tank gauge protocols - connect your existing equipment at less cost Digital and analog I/O connectivity - allows simple tank farm alarm integration Fully compatible with FuelsManager - tank inventory management made easy 830 RTU and gauge configuration data can be exported to other applications, such as Microsoft Excel or Access - document all tank gauge equipment Remote configuration of your tank gauges - means less on-tank activities, resulting in less personnel risk Applications The 830 Remote Terminal Unit (RTU) supports up to four individual expansion interface modules that can interface to virtually any tank gauge on the market. Each interface module will scan all the connected gauges for measured data, such as level, temperature, density, water level and alarms. The 830 RTU also connects to most types of sensors or actuators on your site, and to PLCs and DCS computers. All information obtained can be uploaded to the host system for inventory, alarm and control purposes.

2 +24V +5V +5V -5V CPU COMM I/O ERROR 830 RTU Function and System Design The Remote Terminal Unit (830 RTU) serves as an effective solution in SCADA or standalone control applications by integrating automatic tank gauge communications. Digital, analog and serial I/O interface boards further enhance the 830 RTU into an extremely capable and compact solution for control applications. DC power connections (J2) Intrusion alarm connector I/O expansion module I/O expansion module Communications connections for optional HART interface (J4) The 830 Remote Terminal Unit RS-232-COM 0 2 communications connections (J5-J7) 4 slotted mounting holes to accommodate installation AC power connection (J3) cover I/O expansion module I/O expansion module RS-485 COM and 2 communications connections (J8-J0) Intelligent Architecture The 830 RTU supports up to four interface modules. Each module has its own processor for fast and reliable field data scanning. An internal high speed serial data link communicates the data into a central database. The modules make configuration of the internal 830 RTU database simple and straightforward. Multiple host communication ports offer windows into all the realtime data for up-linking to one or multiple host computers. Field I/O Communication A full range of I/O interfaces is available for the 830 RTU, offering connectivity to virtually every type of signal encountered in industrial environments. The 830 RTU uses standard transmitter signal levels to interface with: Analog input signals, such as 4-20 ma, -5 or 0-0 volts Digital I/O with isolated solid state relays for connection to 5/24 V DC and 20/240 V AC High frequency pulse input for totalization 4-20 ma and 0-0 V analog outputs Expansion s A range of modules is available for interfacing to nearly any brand of tank gauge equipment or technologies, making it possible to integrate float and tape transmitters, HTG, servo, magnetostrictive and radar gauges. This allows direct gauge communication, making communication protocol converters superfluous and combining all equipment into one tank inventory system. The 830 RTU can accommodate a maximum of four expansion modules in four slots. The right most column indicates how many slots are used per module type.

The 830 RTU can be installed in a variety of industrial environments of a non-hazardous nature. For operation within hazardous areas (FM or CSA Class I Div. 2), the 830 RTU must be installed within a NEMA 4 enclosure. Order code NEMA 4 Enclosure for Class I Div 2 operation Description " x 20" x 8" (60 x 508 x 203 mm) " x 24" x 8" (508 x 60 x 203 mm) with 48V DC supply " x24" x 6" (60 x 60 x 52 mm) with 24V DC supply and Modem " x 20" x 8" (60 x 508 x 203 mm) with Front Panel Display, no Power Supply Operation Configuration and Programming Remote programming can be accomplished from the host or locally using a PC with the Windows-based configuration program ViewRTU. This tool simplifies configuration and diagnostics, allowing uploading of final equipment configurations. Reports can also be generated via a built-in function to assist in documentation. Software Functionality 830 RTU software blocks are built-in, providing a broad range of complex, but commonly needed functions, such as: Analog scaling - maps 4-20 ma values into a digital format for host applications Flow measurement and totalization - simplifies the implementation of flow computations Digital alarm handling - offers the possibility of linking alarm inputs to outputs, such as level switch inputs to claxon or siren outputs Pump/valve acquisition and control - allows easy implementation of pump/valve status to the host system or remote control for pumps and motor operated valves Technical Information 3
