★★★Product detail：

The P0916QD contains eight 0-20 mA analog output channels. In situations where control system reliability is
important, the P0916QD may have a redundant module installed. This permits all eight outputs to maintain
operation in the presence of a single fault and during the time that the suspect module is removed and
replaced. The 0-20 mA signals are electrically compatible with HART® field devices

OVERVIEW
The P0916QD, 0 to 20 mA Output Module contains
eight channels. The outputs are galvanically isolated
from other channels and ground. The module can be
used as a single unit, or as a redundant pair (two
P0916QDs).
When used as a redundant pair, field output signals
are wired to one common termination assembly (see
Figure 1). Each module in the pair independently
holds the output(s) at its specified output value(s)

P0916QD

FEATURES
The key features of the P0916QD are:
 Eight 20 mA DC analog output channels
 Each output channel is galvanically isolated
 Single or redundant modules
 Rugged design suitable for enclosure in Class G3
(harsh) environments
 Termination Assemblies (TAs) for locally or
remotely connecting field wiring to the FBM237
 TA for use with Output Bypass Station to
maintain outputs during maintenance operations
 3-tier termination assembly for per channel
internally and/or externally loop powered
transmitters.
 The P0916QD is electrically compatible with
standard HART signals.

REDUNDANT ANALOG OUTPUTS
A redundant analog output function block, AOUTR, is
used for each redundant pair of outputs. The AOUTR
block handles output writes and initialization logic for
the redundant channels. On each execution cycle
identical output writes are sent to both modules, fully
exercising the fieldbus and the logic circuitry of each
module. When a failure is detected in one of the
modules, its output is driven to 0 mA and the
corresponding channel in the good module
automatically continues supplying the proper current.
Each output channel drives an external load.
Transmitter power from each module is diode OR’d
together in the redundant adapter to assure
redundant power. The microprocessor of each
module executes the analog output application
program, plus security routines that validate the
health of the module.
Configurable options in the modules include Fail-Safe
Action (Hold/Fallback), Analog Output Fail-Safe
Fallback Data (on a per channel basis), Fieldbus Fail
Safe Enable, and Fieldbus Fail-Safe Delay Time. The
Analog Output Fail-Safe Fallback Data option must
be set for 0 mA output. This removes one of the pair
of output channels from service for detectable
problems such as a module not properly receiving
output writes, or not passing security tests on FBM
microprocessor writes to output registers. Setting of
the Analog Output Fail-Safe Fallback Data option for
0 mA output also minimizes the possibility of a “fail
high” result
