The X20AO2632 (X20 AO 2632) is a high-precision, dual-channel analog output module developed for the B&R X20 System architecture. Designed for process critical applications including turbine governor control, proportional valve positioning, and high-speed servo drive velocity referencing, this module provides highly accurate control signal generation.
By incorporating a high-speed digital-to-analog converter (DAC) that operates with a 16-bit resolution, the X20AO2632 delivers a stable output range of either $\pm$10 V or 0 to 20 mA. Signal conversion takes just 50 $\mu$s for all channels simultaneously. This rapid conversion execution combined with the integrated NetTime hardware synchronization protocol makes the module perfect for tight, deterministic closed-loop architectures where minimal processing jitter and strict temporal alignment are required to maintain process stability.
The physical interface provides the flexible distribution of voltage and current signals via independent, dedicated terminal connections. For voltage configurations, the conversion resolution is established at $\pm$15-bit, while current configurations utilize a native 15-bit data structure.
To prevent erratic machine behavior during system initialization, the module is equipped with an internal electronic enable relay. This relay physically disconnects the output circuitry from external field devices during the controller boot sequence, ensuring that uncalibrated or transient voltages do not reach connected actuators before the central application achieves a stable running state.
| Engineering Metric | Parameter Value |
| Model | X20AO2632 |
| Brand | B&R (Automation) |
| Origin | Austria |
| Module Configuration | 2 Analog Outputs ($\pm$10 V or 0 to 20 mA) |
| Converter Resolution | Voltage: $\pm$15-bit / Current: 15-bit (16-bit native) |
| Conversion Time Rate | 50 $\mu$s for all outputs simultaneously |
| Settling Time Bounds | 500 $\mu$s over full range (Revision H0 and higher) / 1 ms (Prior to Rev. H0) |
| Boot Protection Mechanics | Internal electrical enable relay for controlled power-up |
| Bus Power Consumption | 0.01 W |
| Internal I/O Power Draw | 1.1 W |
| Shipping Weight | 2.0 kg |
How do the different revisions of the module affect system response time?
Hardware revision codes older than H0 require a 1 ms settling time across the entire signal range. Revision H0 and later incorporate upgraded internal electronics that halve this value to 500 $\mu$s. If your process requires high-frequency adjustments, ensure your physical spare parts inventory matches the updated revision status.
How does the internal enable relay manage safety during a system crash?
The internal enable relay is coupled directly to the module's watchdog and communication monitoring circuits. If the central PLC goes offline or backplane communication is lost, the relay immediately opens. This drops the field outputs to an unpowered state rather than holding a potentially dangerous stale analog value.
What elements make up the listed 2.0 kg shipping weight?
The 2.0 kg shipping specification represents the complete heavy-duty logistical packaging setup. The module is shipped enclosed in thick anti-static shielding film, placed inside custom high-density molded shock-insulation cavities, and boxed with structural cardboard inserts to safeguard the delicate analog components against severe physical vibration during transit.
Dedicated Terminal Selection for Signal Types: The module handles voltage ($\pm$10 V) and current (0 to 20 mA) outputs through distinct terminal connection pins. Verify your field device electrical requirements and map the signal wires precisely to the designated terminals. Connecting a low-impedance current loop to a voltage terminal configuration can result in internal component stress.
Analog Shielding and Ground Loop Prevention: Use high-quality twisted-pair shielded instrumentation cable for all analog output signal paths. Terminate the shield braid exclusively at one end—preferably at the control enclosure's single-point grounding rail—using a low-impedance clamp. Grounding both ends can create ground loops that introduce electrical noise into the 16-bit analog signals.
Thermal Settlement and Airflow Clearances: Maintain standard vertical alignment on the DIN rail with at least 30 mm of free space above and below the module assembly. Proper ventilation ensures the internal DAC components operate within stable thermal margins, preventing thermal drift from compromising signal accuracy across continuous duty cycles.
