  Product Description

  The AO845/AO845A analog output module suitable for single or redundant applications has 8 unipolar analog output channels.The module periodically performs self diagnosis.Module diagnosis includes:

  If the process power supply that provides voltage to the output circuit is too low,or the output current is less than the output set value and the output set value>1 mA(open circuit),an external channel error will be reported(only on active channels).

  If the output circuit cannot provide the correct current value,an internal channel error will be reported.In redundant pairing,the ModuleBus master station will command the module to enter an error state.

  If there are output transistor errors,short circuits,checksum errors,internal power supply errors,status link errors,watchdog or incorrect OSP behavior,a module error will be reported.

  Features and advantages

  8 4...20 mA channels

  Suitable for single or redundant applications

  1 set of 8 channels isolated from the ground

  Analog input short circuit protection to ZP or+24 V

  HART Direct Communication

  advantage

  A cost-effective solution that effectively meets all the needs of on-site equipment,including basic analog and digital I/O,as well as intrinsic safety and high integrity solutions.

  Highly modular,can be combined into various applications,from highly centralized to highly dispersed.

  Support industrial standard fieldbus PROFIBUS DP,while also compatible with non ABB controllers;Also supports ABB's Advanced fieldbus 100

  It can be transparently configured as a part of the relevant controller,just like local I/O,without the need for additional knowledge or skills.

  Comprehensive diagnosis,module hot swapping,and redundancy solutions help maintain improved product performance

  AO845A eA ABB analog output redundancy is designed to provide redundant analog output signals to ensure high system availability in Industrial control system.It supports up to 2 redundant output channels and provides diagnostic functions that are easy to maintain and troubleshoot.In addition,it can be configured for SIL 2 security applications.

  application area

  Industrial control system,process control,safety application.
