ABB | 3BSE045584R1 | AO845A Analog Output Redundant or single

The AO845A/AO845 Analog Output Module for single or redundant applications has 8 unipolar analog outputchannels. The module performs self-diagnosticcyclically.The module has HART pass-through functionality. Only point to point communication is supported. The output filter must be enabled on channels used for HART communication. Five different types of MTUs can be used for single applications. The TU830/ TU833 Extended MTU and the TU810 (or TU814) Compact MTU enables wire connection to the devices without additional terminals. The TU812 Compact MTU has a D-Sub 25 pin (male) connector for connection to the process. For redundant applications there are three types of MTUs, TU842/TU852 for mounting on a horizontal DIN rail and TU843 for mounting on a vertical DIN rail. Shielded field cables for process connections are required if HART is used.

AO845A is in S800 I/O family. S800 I/O with Fieldbus Communication Interface CI801 and I/O Modules Mounted on Compact Type of Termination Units.The S800 I/O is distributed as modular I/O that communicates with numerous controllers over Advant Fieldbus 100 (AF100), PROFIBUS-DP, or directly. The S800 I/O provides easy installation of the I/O modules and process cabling. It is highly modularized and flexible so that I/O modules can be combined to suit many applications. The S800 I/O can be mounted in many configurations to fit most requirements
