AO820 3BSE008546R1 ABB Analog Output 4 ch S800 I/O 0…20 mA Module
AO820 3BSE008546R1 ABB Analog Output 4 ch S800 I/O 0…20 mA Module
The ABB AO820 (Order Code: 3BSE008546R1) is a high-precision 8-channel analog output module designed for the AC 800M programmable automation controller (PAC) system. As a core component of ABB’s Industrial IT and System 800xA architecture, this I/O module delivers reliable, scalable signal generation for controlling actuators, valves, drives, recorders, and other field devices in demanding process and factory automation applications.
Supporting freely configurable per-channel output ranges—including ±10 V, 0–10 V, 0–20 mA, and 4–20 mA—the AO820 adapts to a wide variety of analog control requirements without requiring external signal conditioners. Each channel features galvanic isolation from the backplane and other channels (group isolated), ensuring robustness against ground loops, electrical noise, and transient surges common in industrial environments.
