4 56 XARTU/1 Manual Copyright 2015 Eagle Research Corporation Page | 4 Introduction Overview The XARTU/1 Remote Terminal Unit (RTU) is a low-cost version of the XA Series family of products. It is an intelligent, compact, rugged, and reliable industrial microprocessor-controlled computer designed for real time remote data acquisition and control applications. It can execute multiple processes including tasks such as complex math functions, control algorithms, etc., without host intervention. Flexibility, expandability, and reliability are the major factors in the XARTU/1 design philosophy. It is a balanced system, featuring flexible memory, I/O, power, and communications schemes including support for HEXASCII, MODBUS, and various other custom protocols upon request.

5 A harsh environment tolerance is also one of the XARTU/1 strengths. The operating temperature can range from -40 C to 70 C (-40 F to 158 F), and the XARTU/1 is housed in a fiberglass NEMA 4X enclosure. This allows the RTU to exist where the work must be done, eliminating costly signal conditioning or expensive long sensor runs. The XARTU/1 , normally fed with a 7-30 VDC supply, employs a low-power CMOS design. An optional 120/240 VAC unit includes an uninterruptible power supply. Should it lose power, the RTU will sense the failure, automatically switch to battery power, and continue to operate at full capacity. Other supply options include solar arrays and thermoelectric generators for sites without conventional power. The standard XARTU/1 configuration includes one modem port, two serial ports, six analog inputs, and five multi-purpose digital I/O lines.

6 With optional modules, the XARTU/1 can be expanded to six serial ports and eight analog outputs. The optional operator interface is a two-line, 32-character liquid crystal display, and 25-key keypad with ten user-definable function keys. This allows users to examine and/or change process data and diagnose problems at the remote site without a local host or terminal. The XARTU/1 can calculate natural gas corrected volumes using AGA-3, AGA-5, AGA-7, AGA-8, and NX-19 reports, and is fully compatible with Eagle Research s entire family of products. Eagle Research is committed to providing a complete solution for all gas flow, steam, and control applications. RELIABILITY The XARTU/1 is ruggedly built to perform in a variety of industrial environments.

7 Care is taken to maximize reliability by applying a urethane conformal coating to all circuit boards, utilizing a hermetically sealed keypad and display, and providing NEMA 4X packaging. XARTU/1 Manual Copyright 2015 Eagle Research Corporation Page | 5 Hazardous Location Classifications The XARTU/1 is designed and approved for mounting in Class I, Division 2 hazardous area locations (refer to the NFPA Electrical Code Book). FOUR-YEAR WARRANTY Eagle Research Corporation warrants the products it manufactures to be totally free from any defects in materials and workmanship under normal operation and use. Eagle Research agrees to repair or replace any instrument that is defective due to faulty workmanship or material, if returned to our factory with shipping charges prepaid, within four years of original purchase.

8 RETURNS When a faulty product cannot be repaired in the field, contact Eagle Research Corporation for an RMA number and for return information. Packaging and shipping criteria will be established at that time. *IMPORTANT* REMOVE ANY REPLACEABLE BATTERY OR BATTERY PACK FROM ANY UNIT PRIOR TO ITS RETURN SHIPPING. DAMAGE CAUSED BY LOOSE BATTERIES WITHIN UNITS WILL NOT BE COVERED BY THE MANUFACTURER, AND MAY VOID ANY WARRANTY THE UNIT IS STILL UNDER. ENCLOSURE SECURITY Quick-release door latches that may be padlocked are standard features of the XARTU/1 to prevent unwanted users from opening the enclosure. As an option, a magnetic door-ajar switch may be installed to initiate an alarm when the unit s door is opened.

9 Features Description Input Power 7-30 VDC. Two battery inputs on MTA connectors. One power supply / rechargeable battery input on screw terminals. One solar power input on screw terminals Consumption 5 AH battery, 2-hr charging per day @ 50 mA charge rate. 1 mA average current. Less than 100 uA sleep current Power Monitoring Supply voltage monitoring through a/d with low supply voltage Interrupt Backup Battery VDC lithium backup battery: 10 years typical backup of database and time/date during normal use Processor Phillips P51 XAS3 high performance 16-bit microcontroller running at MHz Memory 512K x 8 remotely-programmable FLASH program memory 512K x 8 battery-backed RAM data memory Real time Clock Battery-backed, quartz crystal controlled; +/- 1 sec/day typical accuracy; programmable time scheduled interrupt capability Internal Inputs One ambient temperature input; one supply voltage input Pulse Inputs Four pulse inputs, software programmable for Form A or C; high or low speed.

10 Each counter is a six-digit (0-999999) hardware counter with programmable interrupt support. Can be used for simple pulse accumulation, and for more complex applications such as card readers Digital I/O s Five multi-purpose memory-mapped digital I/O lines. High-level functionality including pulse inputs, PWM (pulse width modulation) outputs, and complex custom inputs/outputs. Two I/O lines are connected to field terminals through standard OPTO-22 modules. The other three I/O lines can be used as either Form C or A relay outputs (solid state 100 mA max AC/DC) or status inputs (50 V max DC only). Analog Inputs Six general-purpose analog inputs, 12-bit resolution, analog sampling, software calibration. Nominal input ranges VDC. A 250-ohm resistor in socket allows 4-20 mA or 0-5 VDC input for each channel.
