The ABB AO1032B is a high-precision Analog Output Module designed for the S800 I/O system, often used in conjunction with Advant Controllers and AC 800M series. This module provides 8 channels of isolated analog output signals, typically used to control actuators, variable speed drives, or positioners. It is engineered for industrial environments that require high accuracy and galvanic isolation between the control system and the field equipment, ensuring that noise or electrical faults in the field do not damage the central processing unit.
Product Specifications
Product Name: Analog Output Module Model Number: AO1032B Part ID: 3BSE018283R1 Number of Channels: 8 Isolated Channels Output Range: 0 to 20 mA, 4 to 20 mA, or 0 to 10 V DC Resolution: 12-bit / 14-bit (configuration dependent) Galvanic Isolation: 50 V continuous (group-wise isolation) Dimensions: 185 mm x 45 mm x 125 mm Weight: 0.35 kg Country of Origin: Estonia / Sweden

Application Areas
The AO1032B is a versatile module found in various process control architectures:
-
Valve Actuation: Providing 4-20mA signals to control the opening percentage of pneumatic or electric control valves.
-
Motor Control: Interfacing with Variable Frequency Drives (VFDs) to regulate the speed and torque of industrial motors.
-
Process Heating: Sending setpoint signals to thyristor power controllers for temperature regulation in furnaces.
-
Dampers and Louvers: Managing air-flow control in HVAC and boiler combustion systems.
Usage Instructions
To ensure the stable performance of the AO1032B:
-
Mounting: Snap the module onto the appropriate S800 I/O Terminal Base (e.g., TU810 or TU812). Ensure the mechanical locking tab is fully engaged to establish a reliable connection to the ModuleBus.
-
Configuration: Use the ABB Control Builder M software to define the output range (voltage or current) for each channel. Ensure the software “Hardware Definition” matches the physical module version.
-
Wiring: Use twisted-pair cables for analog output signals. To prevent ground loops and signal interference, the cable shield should be grounded at only one point, typically at the I/O cabinet entry.
-
Diagnostics: Monitor the “Fault” and “Warning” LEDs on the front of the module. A blinking “Run” LED indicates the module is communicating correctly with the CI854 or CI860 bus coupler.
Q&A – Frequently Asked Questions
What is the difference between the AO1032 and the AO1032B? The “B” version typically indicates a hardware revision that offers improved component longevity or updated manufacturing standards, while remaining fully backward compatible with the standard AO1032 software drivers.
Does this module require an external 24V power supply? Yes, the AO1032B requires an external 24V DC supply to power the output circuitry and provide the necessary current for the 4-20mA loops.
How does the module behave upon a communication loss? The AO1032B can be configured via software to either “Freeze” (hold the last value), “Go to Zero,” or “Go to a Predefined Safe Value” if communication with the controller is interrupted.
Can I mix current and voltage outputs on the same module? Yes, the channels are individually configurable, allowing you to run 4-20mA signals on some channels and 0-10V signals on others simultaneously.
