          PRODUCT DESCRIPTION

          ABB AO845A 3BSE045584R1 redundant hart analog output

          ABB AO845A (3BSE045584R1) is an S800 analog output module with eight 4–20 mA channels, 12-bit resolution and HART pass-through communication. It supports single or redundant operation and provides groupwise isolation from ground for process-control output loops.

          The module includes cyclic self-diagnostics, short-circuit-protected current outputs, a 10 ms update cycle and support for compatible S800 module termination units. Verify the full article number, MTU selection, load limits and installed redundancy configuration before replacement or commissioning.

          S800 I/O ANALOG OUTPUT

          Integrate AO845A with the verified S800 I/O configuration

          ABB AO845A is an S800 analog output module for eight 4–20 mA channels with HART pass-through communication. It can operate in single or redundant configurations.
          The module must be installed with a compatible S800 module termination unit and matched to the controller, ModuleBus arrangement, field wiring and external process power used by the project.
          Commissioning should verify channel scaling, loop load, HART communication, redundancy status and module diagnostics. ABB specifies a maximum 750 Ω output load and a 10 ms update cycle.

          Features:

          • Eight 4–20 mA output channels
          • Single or redundant S800 operation
          • Compatible MTU and loop load must be verified
          The ABB AO845A / 3BSE045584R1 S800 I/O module should be matched to the compatible MTU, field wiring and controller configuration before system integration and commissioning.
          INTERCHANGEABILITY

          Match the complete AO845A identity before replacement

          Replace AO845A only after confirming the complete article number 3BSE045584R1 and the installed S800 I/O configuration. Similar analog output modules can have different signal ranges, HART functions or redundancy behavior.
          Verify the compatible MTU, keying code DB, field wiring, process power, output load and redundancy pairing before removal. Preserve the controller configuration and record the existing channel assignments.
          After installation, confirm module status, channel diagnostics, loop current, HART pass-through and failover behavior where redundancy is used. Do not treat AO815, AO820 or another S800 module as a direct substitute without engineering verification.

          Features:

          • Match article number 3BSE045584R1
          • Confirm MTU, keying and field wiring
          • Test diagnostics, outputs and redundancy after power-up
          The ABB AO845A / 3BSE045584R1 S800 I/O module requires replacement verification based on the complete article number, MTU, wiring and controller configuration before commissioning.
