Proven Application Environments
- Packaging Machinery: Precise tension and pressure monitoring via 4–20 mA transmitters on form-fill-seal lines.
- Plastics & Extrusion: Multi-zone temperature acquisition from thermocouple transmitters with ±10 V output.
- Hydraulic Press Control: Real-time pressure transducer feedback for closed-loop force regulation.
- Conveyor & Material Handling: Load cell signal acquisition for dynamic weighing and sorting systems.

- Water Treatment: Flow meter and level transmitter signal conditioning in continuous process plants.
- Semiconductor Fab Equipment: High-accuracy analog acquisition for process gas flow and chamber pressure.
Engineering Advantages
- Dual-Mode Input Flexibility: Each channel independently configurable for voltage (±10 V) or current (0–20 mA) without hardware jumpers — reduces BOM complexity and cabinet wiring time.
- X2X Link Bus Integration: Deterministic, high-speed data transfer to the CPU with guaranteed cycle-time synchronization — critical for motion-coordinated analog feedback loops.
- Compact 12.5 mm Pitch: Ultra-slim form factor maximizes I/O density in space-constrained control cabinets.
- Hot-Swap Capable: Module replacement without full system shutdown minimizes production downtime during maintenance.
- Integrated Diagnostics: Per-channel wire-break and overrange detection with status flags accessible via Automation Studio — eliminates need for external signal conditioners.
- Galvanic Isolation: Field-side isolation protects the CPU and backplane from ground loops and transient surges common in industrial environments.
System Architecture & Signal Flow
The X20 AI 4622 mounts directly onto the X20 bus module (X20BM01 or compatible) and communicates via the X2X Link at up to 100 Mbit/s. Analog signals enter through the terminal block, pass through a multiplexed ADC with per-channel sample-and-hold, and are digitized to 12-bit resolution. The digital values are mapped to process image variables in Automation Studio (AS) and are accessible within the same PLC scan cycle. Channel configuration (voltage/current mode, filter settings) is performed entirely in software via AS I/O configuration — no physical DIP switches or jumpers required.
Signal chain: Field Sensor → Terminal Block → Input Protection → MUX → ADC (12-bit) → X2X Link Frame → CPU Process Image → AS Variable

Technical FAQ
Q: Is the X20 AI 4622 compatible with X20 CP1586 and CP3586 CPUs?
A: Yes. All X20 CPUs with X2X Link support are compatible. Confirm your AS hardware configuration includes the correct module GSD/hardware description file.
Q: Can I mix voltage and current channels on the same module?
A: Yes. Each of the 4 channels is independently configurable in Automation Studio — no hardware modification required.
Q: What is the maximum cable length for analog inputs?
A: B&R recommends shielded twisted-pair cable up to 30 m for voltage inputs and up to 100 m for current loop (4–20 mA) inputs. Shield should be grounded at one end only.
Q: Does the module support HART protocol?
A: No. The X20 AI 4622 is a standard analog input module and does not support HART multiplexing. For HART-enabled analog acquisition, refer to the X20 AI 4632HF.
Q: What happens if a channel input exceeds the rated range?
A: The module sets an overrange diagnostic flag in the process image. The ADC saturates at full scale; no hardware damage occurs within ±15 V / 30 mA transient limits.
Q: Can I order with a specific firmware version?
A: Konmask will confirm available firmware revisions at time of order. Specify your AS version requirement when requesting a quote.
