The Model 56 advanced analyzer supports continuous
measurement of analytical inputs from one or two sensors. The
modular design allows signal input boards to be field replaced,
making configuration changes easy. The high resolution
full-color display gives unsurpassed visibility and functionality for
analytical instrumentation.
Full Color Display:The high resolution full-color display allows easy
at-a-glance viewing of process readings – indoors or outdoors. Six
additional process variables or diagnostic parameters are
always displayed for quick determination of process or sensor
condition.
Menus: Intuitive screens for easy configuration and calibration.
Quick Start and all menu screens are available in multiple local
languages. Alpha-numeric keypad allows easy entries during
configuration and calibration.
Quick Start Programming: Simplified Quick Start screens
appear the first time the unit is powered. The instrument autorecognizes
each type of measurement board and prompts the
user to configure each sensor loop in a few quick steps for
immediate live readings.
User Help Screens. A complete user guide and trouble-shooting
manual is embedded in the instrument’s memory and easily
accessed via the INFO key on the keypad. Detailed instructions
and troubleshooting tips are intended to provide adequate
guidance to resolve most problems on site.
Local Languages: Rosemount Analytical extends its worldwide
reach by offering nine menu languages – English, French,
German, Italian, Spanish, Portuguese, Chinese, Russian and
Polish. Every unit includes user programming menus; calibration
routines; and faults and warnings in all nine languages.
Modular, Scalable, Flexible: Slide-in measurement boards
allow easy sensor wiring and configuration changes in the field.
There are no limitations for measurement or communication
configurations.
Device Security: Two levels of security access are available.
Program one access code for routine maintenance and hold of
current outputs; program another access code for all configuration
menus and functions.
Diagnostics: The analyzer continuously monitors itself and the
sensor(s) for fault and warning conditions. A display banner
flashes red to indicate a Fault condition and yellow for a
Warning condition to visually alert field personnel. Details and
troubleshooting information for any specific fault or warning
can be readily accessed by pressing the INFO key.
Current Outputs: Every unit includes four actively powered
4-20 mA or 0-20 mA electrically isolated current outputs giving
the ability to transmit the measurement value and the temperature
for both sensors. Users have wide latitude to assign any
measurement value or live diagnostic to any current output for
reporting.
Advanced Features
Process trending graphs: High-resolution color graphs of
measurement data can be displayed on-screen to pinpoint
process disruptions or measurement problems and to estimate
probe maintenance frequency. The analyzer gives the user the
ability to zoom in to a specific narrow timeframe of process
measurements for detailed on-screen evaluation.

Process trends of any two measurements, temperature or
live diagnostics
Data logger and Event Logger/Audit Trail: Extensive onboard
data storage captures measurement data from both channels,
including temperature every 30 seconds for 30 days for
on-screen display or local upload to a USB 2.0 memory device.
300 significant analyzer events are recorded including start-up
time, calibrations, hold outputs, configurations, alarms, power
interruptions, faults, and more. All process data and events are
time/date stamped.
USB 2.0: Local data transfer of process data and events using a
standard USB memory device. Cleanly pre-formatted EXCEL
data is useful for evaluation of process data on a computer and
identification of critical alarm or fault events.
Advanced control: Any current output can be programmed for
PID functions. Proportional, Integral and Derivative settings
allow the analog current outputs to adjust a control device that
has continuous adjustability. PID is typically used on modulating
control devices such as automated control valves or variable
speed pumps.
Alarm relay capabilities: Four SPDT alarm relays are fully
assignable and programmable to trigger alarms upon reaching
measurement, diagnostics setpoints, or fault conditions.
Further relay settings include TPC, synchronized interval timers
and four specialized timer functions described below. All relays
are independently activated. Failsafe operation and programming
of relay default state (normally open or normally closed) is
software selectable.
Timer functions: Four real-time clock relay functions are
implemented including: bleed and feed, day and time interval
timers, delay timer and a flow totalizer. These advanced timer
features support a number of specialized applications that normally
require dedicated timer control devices or DCS programming.
Interval timers set relays by interval time, on-time and recovery time
for discrete on/off control devices based on measurement inputs.
Digital Communications: HART version 5 and 7 digital communications
are available on Model 56. An optional Profibus DP
digital communications board is available for Profibus installations.
HART and Profibus DP configured units will support any
single or dual measurement configurations of Model 56.

HART and optional Profibus DP
Wireless THUM Adaptor compatible:
Enable wireless transmissions of process
variables and diagnostics from hard-to-reach
locations where it is impractical to run wires
for current outputs. When commissioned
with the THUM Adaptor, Model 56 HART
units can communicate on Emerson wireless
networks using HART 7 wireless protocol.
SMART-enabled pH: Rosemount Analytical’s SMART preamplifier
pH capability can eliminate field calibration of pH probes through
automatic upload of calibration data and history – fully calibrating
the pH loop. pH probe changes are literally “plug and play” using
SMART pH sensors with VP cables connections.
Enclosure: The instrument enclosure fits standard DIN panel
cutouts. The versatile enclosure design supports panel-mount,
pipe-mount, and surface/wall-mount installations. Enclosure
