ABB Totalflow XSeries Hardware Overview
Key Takeaway
Complete hardware reference for ABB Totalflow XSeries — XFC and XRC base units, I/O modules, communication ports, power wiring, and field installation.
Quick Answer
The ABB Totalflow XSeries uses a modular architecture with a base unit (XFC or XRC) containing CPU, onboard I/O, serial and Ethernet ports, LCD display, and SD card. Expansion I/O modules add analog, digital, pulse, and temperature channels via the backplane bus.
XFC Base Unit
- CPU with flash memory for program and archives
- Onboard analog inputs (pressure, DP, temperature)
- Digital I/O and pulse inputs for turbine meters
- RS-232 and RS-485 serial ports
- Ethernet port (XSeries models)
- LCD display with keypad for local status and configuration
- SD card slot for extended archive storage
XRC Additions
All XFC features plus expanded I/O capacity, additional serial ports for multi-protocol operation, and TAS programming capability.
I/O Expansion Modules
- Analog input (4-20mA, voltage, internal transducer)
- Digital I/O (relay, transistor)
- Pulse input (turbine meter, high/low frequency)
- Temperature (RTD, thermocouple)
- Pressure transducer interface
Power and Environment
12/24VDC operation, solar-compatible with ultra-low-power modes. Operating temperature -40°C to +70°C for harsh oilfield environments. IP-rated enclosure options for outdoor installation.
Frequently Asked Questions
The XFC base unit includes onboard analog inputs for pressure, DP, and temperature. Additional channels are added via expansion I/O modules on the backplane bus.
Yes. XIO modules connect via the TFIO bus and can be distributed across a field installation away from the XRC base unit.
