New AO845 / AO845A Analog Output Redundant Module 1x8ch Hart
3BSE045584R1 S800 I/O Description of AO845 / AO845A The AO845/AO845A Analog Output Module for single or redundant
applications has 8 unipolar analog output channels. The module
performs self-diagnostic cyclically. Module diagnostics include: - External Channel Error is reported (only reported on active
channels) if the process power supply that supply voltage to output
circuitry is too low, or the output current is less than the output
set value and the output set value > 1 mA (open circuit).
- Internal Channel Error is reported if the output circuit can not
give the right current value. In a redundant pair the module will
be commanded to error state by the ModuleBus master.
- Module Error is reported in case of Output Transistor Error, Short
Circuit, Checksum Error, Internal Power Supply Error, Status Link
Error, Watchdog or Wrong OSP behavior.
