RS-232 and RS-485 communication modules that plug directly into the board. The XRC
output points:
–
5 analog inputs
–
4 DI/PI inputs can be used as high-speed (20KHz) counters, or as status indicators (Selectable Debounce enable/disable)
–
4 digital outputs
–
2 Remote Communication Ports (RS-232 or 485)
–
I/O interface for TFIO interface modules
CPU engine card
The CPU engine card (2102427-xxx) plugs into the XRC
All processor and memory components reside on the CPU engine card. The engine card uses a low power processor running at
192 MHz with 16M SRAM, 32M Flash and 256 bytes of serial E2PROM. A lithium backup battery is located on the main XRC
board. Unplugging the engine card disconnects it from the lithium cell backup and SRAM (historical flow data) is cleared.
Application programs and configuration files are stored in non-volatile Flash.
Communication enclosure
A removable communications enclosure can be provided that has been pre-drilled for mounting many popular communications
devices such as radios, cellular phones, modems, etc. This feature is not available in the XRC
Battery compartment
G4
The XRC system houses an internal main battery.
–
G4
XRC 6490: The battery sets in a central compartment directly behind the battery plate.
–
G4
XRC 6790: The battery sets in a central compartment directly behind a hinged cover plate holding the DIN rail and
installed modular components.
–
G4
XRC 6890: The battery sets on the floor of the main compartment and houses the various optional battery packs that are

available for the XRC
Solar panel
G4
The XRC is configurable for a 10-Watt, 20-Watt or 30-Watt solar panel. The panel is designed for mounting on a 2-inch
extension pipe above the XRC
installations, solar panel chargers must be configured to mount outside of the building.
Additional features
Additional features of the Totalflow System include the following:
–
A Programmable bi-level security system prevents unauthorized communication and configuration of the XRC
section 3.5.6, Bi-Level security system for more information.
–
An internal crystal controlled clock provides a highly stable time base for the system.
–
Optional battery packs extend operation for longer periods without power.
–
Three available charging sources include:
– External solar panel (standard)
– External AC power
– External 24/12 Vdc power
–
The LCD (Liquid Crystal Display) is programmable to allow the monitoring of operations (displays flow rate, volumes, etc.)
–
The rugged, aluminum, powder-coated NEMA 4X enclosure is lockable to prevent internal access.
–
An optional ability allows rapid data collection over several communication links.
–
Additional I/O for valve control, pressure, level monitoring, remote communication, etc. are available.
–
An optional keypad is available.
