B&R X20AI4622 – 4-Channel Analog Input Module | X20 System Platform
Engineering Background
The X20 System is B&R’s flagship modular I/O platform, engineered for high-density, high-speed process control in demanding industrial environments. Designed around a proprietary X2X Link backplane bus, the platform delivers deterministic cycle times and seamless integration with ACOPOS drives, SafeLOGIC controllers, and Automation Studio engineering software.
Product Positioning
The X20AI4622 is a 4-channel analog input module optimized for precision signal acquisition in process automation, machine control, and energy management applications. Its multi-range input capability (voltage and current) and 13-bit resolution make it the preferred choice for procurement engineers specifying reliable, spec-accurate analog front-ends in B&R X20 control architectures.

Proven Application Environments
- Process Automation: Temperature, pressure, and flow signal acquisition via 4–20 mA transmitters
- Machine Control: Servo feedback conditioning and analog setpoint input for motion axes
- Energy Management: Power quality monitoring with ±10 V transducer inputs
- Packaging & Printing: Tension control and web-guide analog feedback loops
- Water & Wastewater: Multi-sensor analog acquisition in distributed I/O topologies
- Semiconductor & Cleanroom: High-precision analog measurement in controlled environments
Engineering Advantages
- Dual-mode input: Voltage (±10 V) and current (0/4–20 mA) selectable per channel — eliminates the need for separate modules in mixed-signal panels
- Deterministic X2X Link bus: Guaranteed cycle-synchronous data transfer with the X20 CPU, critical for closed-loop control
- Compact 12.5 mm pitch: High channel density minimizes cabinet footprint in space-constrained installations
- Automation Studio native: Zero-configuration I/O mapping; hardware tree auto-detection in AS 4.x
- Differential inputs: Superior common-mode noise rejection in electrically noisy industrial environments
- Hot-swap capable: Module replacement without full system shutdown (with appropriate X20 bus base)
System Architecture & Signal Flow
The X20AI4622 plugs directly onto an X20 bus base (e.g., X20BM01, X20BM11), which provides both mechanical mounting and X2X Link electrical connection. Field wiring terminates at the bus base’s screw terminals. The module’s internal ADC samples each of the 4 differential channels sequentially at ≤ 800 µs/channel, converts the result to a 13-bit signed integer, and transfers the process image to the X20 CPU via the X2X Link at the configured bus cycle time (typically 400 µs – 10 ms). In Automation Studio, channels appear as standard REAL or INT variables in the I/O mapping, directly accessible in IEC 61131-3 programs or mapp components.

Technical FAQ
Q: Can I mix voltage and current inputs on the same X20AI4622 module?
A: Yes. Input mode (voltage/current) is configured per channel in Automation Studio via the hardware configuration tree — no hardware jumpers required.
Q: What bus base is required for the X20AI4622?
A: Any standard X20 bus base with the correct terminal type (e.g., X20BM01 for screw terminals, X20BM11 for push-in). The bus base is ordered separately.
Q: Is the X20AI4622 compatible with X20 SafeLOGIC controllers?
A: The X20AI4622 is a standard (non-safe) module. It can coexist on the same X20 backplane as SafeLOGIC modules but its signals are not SIL-rated. For functional safety analog input, specify the X20SAI4622.
Q: What is the maximum cable length for analog inputs?
A: B&R recommends shielded twisted-pair cable ≤ 30 m for voltage inputs and ≤ 100 m for 4–20 mA current loop inputs. Shield should be grounded at one end only.
Q: Do you provide the Automation Studio hardware description file?
A: Yes. The .hw file is included in the standard AS installation. We can also provide the latest B&R firmware package on request.
