ABB AO05 HART Analog Output Module
Product Overview
The ABB AO05 is a high-performance analog output module designed for Symphony Plus controllers. It provides isolated current or voltage outputs with full HART support, making it suitable for advanced process control applications requiring high accuracy, reliability, and enhanced communication.
Key Specifications
-
Output channels: 8 independent isolated high-level analog output channels
-
Programming options: Each channel configurable for current or voltage output
-
Function codes:
-
221 – I/O device definition
-
223 – Analog output/channel configuration
-
-
Calibration: Each output channel reads back the field signal for precise operation, eliminating the need for manual calibration output
Performance Features
-
Enhanced vs. AO02: Higher performance with separate channel isolation and dedicated HART modems for each channel
-
HART communication: Each channel is equipped with an independent HART modem for digital communication alongside analog output
-
Secondary variables: Supports up to 4 secondary variables per channel, for a total of 32 secondary variables across the module
Application
-
