ABB AO845 3BSE023676R1 Analog output short circuit protection

Description

The AO845/AO845A Analog Output Module has 8 analog outputs. State of outputs
can be set to a predetermined (OSP) value if a communication error is detected. The
module has advanced on-board diagnostics and HART pass-through functionality.
It can be used in both single and redundant applications. Nominal output range is:
4…20mA.

Replacement with power applied is
possible.
It may be necessary to set the process
device manually to a safe state before the
module is extracted.
Turning locking mechanism deactivates the
module.

Features
• 8 channels of 4…20 mA outputs.
• For single or redundant applications.
• OSP sets outputs to predetermined state
upon error detection.
• 1 group of 8 channels isolated from ground.
• Analog Output is to be short circuit secured
to ZP or +24 V.
• Advanced on-board diagnostics.
• 12 bit resolution.
• HART pass-through communication.
Description
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.
