Product Overview
The ABB AO810 analog output module (Article No. 3BSE038415R1) delivers eight unipolar analog output channels engineered for precision and reliability in demanding industrial environments. This S800 series module performs cyclic self-diagnostics, including readback verification of serial data to the D/A converters and open-circuit detection. When output supply voltage drops too low, the AO810 reports a module error; channel faults (open circuit for currents above 1 mA) are flagged only on active channels. With its robust design and comprehensive supervision, the AO810 ensures dependable performance in process control and automation systems.

Applications
The ABB AO810 analog output module excels in process control systems where precise current loop outputs are critical. Typical applications include:
-
Valve Positioning: Controlling 4-20 mA signals to position pneumatic or electric valves in chemical plants.
-
Variable Frequency Drives: Sending speed setpoints to VFDs in conveyor systems and pump stations.
-
PID Loop Control: Providing analog output for closed-loop control in temperature or flow systems.
For example, in a water treatment facility, the AO810 can drive multiple dosing pumps while its open-circuit diagnostics immediately alert operators to a broken wire, minimizing chemical waste and downtime.
Installation & Setup
Mount the AO810 in a compatible S800 series I/O chassis. Ensure proper keying (code AE) before insertion. Connect output wiring to the appropriate terminals on the TU810V1 mounting unit. For optimal performance, keep field cable lengths under 600 meters. When connecting loads, verify the supply configuration: if using L1+ only, the load must not exceed 500 Ω; with L2+ supply, loads from 250 to 850 Ω are supported. After installation, perform a loop check to confirm output current matches the setpoint.
Maintenance & Reliability
Routine maintenance is minimal due to the AO810's solid-state design. Periodically inspect cables and connectors for wear or corrosion, especially in harsh environments (the module meets ISA-S71.04 G3 corrosion protection). The module's self-diagnostics and front LEDs (F, R, W, OSP) provide immediate status indication, reducing troubleshooting time. With a power dissipation of only 2.3 W, the AO810 runs cool, extending component life. Its wide operating temperature range (-40 to +70 °C storage) ensures reliability in extreme conditions.
Compatibility & Integration
The AO810 integrates seamlessly into ABB S800 I/O systems. It works with MTU models TU810, TU812, TU814, TU830, and TU833, and is specifically matched with the TU810V1. This module supports 0-20 mA and 4-20 mA signals, making it versatile for various PLC and DCS platforms. Its groupwise isolation from ground helps prevent ground loops in complex installations. For redundancy or high-integrity applications, note that this module does not support HART, SOE, redundancy, or high-integrity configurations.
Buying Guide
Before purchasing, verify your system's compatibility with the AO810 (Article No. 3BSE038415R1). Confirm the required number of channels and output signal types. If you need HART or redundancy, consider other modules. When sourcing, choose a trusted supplier like PLC Source PRO to ensure genuine parts and reliable support. Always check the module's keying code (AE) matches your rack.
