Brand: ABB
Series: S800 I/O (part of ABB’s modular, distributed process I/O system compatible with 800xA and AC 800M platforms)
The AO810V2 module is a precision analog output I/O module used within ABB’s S800 framework. Designed to manage eight unipolar analog output channels (0…20 mA or 4…20 mA), it enables reliable command of external devices such as valves, actuators, or drives. Compact and self-monitored, it fits neatly into control racks while offering built-in diagnostics to ensure safety and uptime.

Ideal for high-precision analog control in:
Process industries—regulating valves, actuators, and control loops through 4…20 mA or 0…20 mA signals
Manufacturing automation—driving analog inputs of control equipment and pneumatic or motorized valves
Oil & gas / chemical sectors—where precise control and diagnostic awareness reduce downtime
Distributed I/O systems—especially in 800xA or AC 800M setups, offering modular expansion and signal integration
Compact and efficient—8 accurate outputs in a small 45 mm module
Reliable diagnostics—cycle self-check, open-circuit alerts, error LEDs, and OSP (Output Safe Position) ensure safety and maintenance clarity
Wide compatibility—fits into S800 racks and pairs with TU810/TU830 termination units
Strong signal integrity—fast update rates (≤ 2 ms), great rise times, and high load capacity
Industrial toughness—IP20 rating, broad temperature range, and certified to CE / UL / ATEX (Zone 2) standards
