SeriesG4 Remote Controllers (XRCG4) enable you to monitor, measure, and control your facilities from anywhere, anytime. Combining unmatched measurement technology with next-generation remote control technology, the XRCG4 can significantly extend the life of your equipment while saving you time and money. Featuring spacious cable routing, large enclosures and powerful battery capacity, the XRCG4 is designed to grow with your business. Upgrades are seamless and simple, so there is no need for costly retraining.
The XRCG4 Series is made up of full-featured units without an integrated Multivariable Transducer (XIMV). In its base configuration, each unit is equipped with standard I/O designed to meet the requirements of many low-cost measurement and automation projects. The base I/O includes five analog inputs (0-10 volts DC), four digital outputs and four digital inputs which can be configured as either status inputs or pulse accumulator inputs.
I/O modules can be added to extend the hardware I/O capability. The XRCG4 6895 accommodates up to 22 TFIO modules. All units except the XRCG4 6895 are powered by an internal battery that can be solar charged (or other suitable DC supply) for remote, unattended operation. Several charging options are available. Communications interface cables and equipment can be installed at the factory, ready for quick installation. Checking and modifying configuration and calibration is accomplished with ABB Totalflow’s PCCU32 laptop software, running on a 32-bit Windows® operating system.
Description
The XRCG4 features a powerful 203Mhz, ARM920T, 32-bit microprocessor and Windows® CE operating system. The XRCG4 utilizes a unique, engine card design. The engine card contains the processor, application firmware and memory components. This allows the user to move the engine card with all programming intact from one device to another, if necessary. The processing and memory capability of this device, allows the user to run more applications faster than ever before. Up to twenty (20) AGA-3 measurement tubes performing full calculations once a second and twenty (20) advanced Plunger Lift applications may be running in one XRCG4. In it’s base configuration, this unit is equipped with standard I/O designed to meet the requirements of many low cost automation and measurement projects. The base I/O includes 5 analog inputs (0 to 10 V DC), four (4) digital outputs and four (4) digital inputs which can be configured as either status inputs or high speed, pulse accumulator inputs. I/O modules can be added to extend the hardware I/O capabilities.
XFCG4 and XRCG4 devices are based on the same software environment. Applications available in one are also available in the other, including
custody transfer measurement applications. The two significant differences between XFCG4 and XRCG4 devices concerns their hardware:
XFCG4 devices include an integral multivariable transducer, and XRCG4 devices do not. There are more base I/O points on XRCG4 devices than on XFCG4 devices
Multi-tube capability (up to 20 tubes) is available in each unit and is easily invoked with a few configuration changes and interface connection to external transducers, either digital or analog.
Each unit is powered by an internal battery that can be solar charged (or other suitable DC supply) for remote unattended operation. Several charging options are available.
Communications interface cables and equipment can be installed at the factory, ready for quick field installation. Checking and modifying configuration and calibration is performed with ABB’s Totalflow PCCU32 laptop software running on a 32-bit Windows operating system.
In addition to the local configuration port, two serial communications ports are supplied with the standard unit. These ports are modular and user selectable for RS-232 and/ or RS-485. An additional port may be added using a TFIO communications module.
One integrated, 10Base-T Ethernet port for network connectivity is standard, and a USB port for Flash download and local configuration is available as an option.
