Product Description:

The 2AO300.6 is an analog output module manufactured by B & R Automation for the System 2010 Controllers series. It converts numeric setpoints generated by the CPU into stable bipolar voltages, allowing the controller to drive actuators, reference inputs, and other field devices that rely on a precise ±10 V command signal. By providing this digital-to-analog interface inside the same backplane, the module helps reduce wiring, simplifies cabinet layout, and keeps response latency low in industrial automation cells. This arrangement is useful when a control system must send smooth analog references to several devices without adding a separate external converter.

Inside the 40 mm wide housing, the module offers 16 bipolar voltage outputs, so one slice can support multiple axes or process loops. Each channel delivers a full-scale swing of ±10 V, compatible with standard drive and instrumentation inputs. A converter with 12 bit resolution divides that span into 4096 discrete steps, while a conversion time of 250 µs keeps new setpoints synchronized with fast machine cycles. At 20 °C, the deviation from ideal remains within ±0.25 %, which helps maintain predictable analog commands, and a first-order low-pass filter at 1000 Hz attenuates switching noise without sacrificing control bandwidth.

Accuracy stays within ±0.5 % across the broader 0 °C to 60 °C operating range, maintaining loop stability as cabinet temperature drifts. Each output can source or sink up to ±10 mA into loads of at least 1 kΩ, and fault current is limited to ±15 mA to protect the driver stage during short circuits. Overall demand remains below 10 W max, easing power-rail sizing when the module is mounted on BP200, BP201, or BP210 base plates. RPS isolation separates system power from field wiring, while the lack of per-channel isolation keeps the footprint compact for dense rack installations.
