The ABB AO820 3BSE008546R1 AO820 Analog Output is a high-performance analog output module engineered to support precise process control in demanding automation environments. Featuring four bipolar analog output channels, it offers exceptional flexibility by allowing each channel to be individually configured for current or voltage output through simple software settings.

Each channel of the AO820 3BSE008546R1 ABB  I/O Systems supports ranges such as -20 mA to +20 mA, 0–20 mA, 4–20 mA, or voltage outputs of -10 V to +10 V, 0–10 V, and 2–10 V. Separate terminal sets for voltage and current outputs ensure safe, tailored wiring to suit application needs. The module also provides robust diagnostics, including continuous open-circuit checks and process voltage supervision that promptly signals any errors via the ModuleBus.

Engineered for reliability, the GALV Isolated Bipolar AO Module AO820 3BSE008546R1 delivers 12-bit resolution (including sign), under/over range capability of ±15%, and a fast rise time of under 0.7 ms. It operates with output loads of ≤550 Ω for current and ≥5 kΩ for voltage, while maintaining low temperature drift at a maximum of 90 ppm/°C.

Certified with a rated insulation voltage of 50 V and typical power dissipation of just 6 W, the 3BSE008546R1 AO820 Analog Output 4 channels ensures stable, galvanically isolated outputs. By combining speed, precision, and advanced diagnostics, the ABB Analog Output Channel AO820 3BSE008546R1 stands out as an essential component in ABB’s automation solutions.
