FEATURES AND APPLICATIONS
The Model 1056 dual-input analyzer offers single or
dual sensor input with an unrestricted choice of dual
measurements. This multi-parameter instrument offers
a wide range of measurement choices supporting most
industrial, commercial, and municipal applications.
The modular design allows signal input boards to be
field replaced making configuration changes easy.
Conveniently, live process values are always displayed
during programming and calibration routines.

QUICK START PROGRAMMING: Exclusive Quick
Start screens appear the first time the Model 1056
is powered. The instrument auto-recognizes each
measurement board and prompts the user to configure
each sensor loop in a few quick steps for immediate
deployment.

DIGITAL COMMUNICATIONS: HART and Profibus
DP digital communications are available. Model 1056
HART units communicate with the Model 375 HART®
hand-held communicator and HART hosts, such as
AMS Intelligent Device Manager. Model 1056 Profibus
units are fully compatible with Profibus DP networks
and Class 1 or Class 2 masters. HART and Profibus
DP configured units will support any single or dual
measurement configurations of Model 1056.

MENUS: Menu screens for calibrating and programming
are simple and intuitive. Plain language prompts and
help screens guide the user through these procedures.
DUAL SENSOR INPUT AND OUTPUT: The Model
1056 accepts single or dual sensor input. Standard
0/4-20 mA current outputs can be programmed to
correspond to any measurement or temperature.
ENCLOSURE: The instrument fits standard ½ DIN
panel cutouts. The versatile enclosure design supports
panel-mount, pipe-mount, and surface/wall-mount
installations.
ISOLATED INPUTS: Inputs are isolated from other
signal sources and earth ground. This ensures clean
signal inputs for single and dual input configurations.
For dual input configurations, isolation allows any
combination of measurements and signal inputs without
cross-talk or signal interference.
TEMPERATURE: Most measurements require temperature
compensation. The Model 1056 will automatically
recognize Pt100, Pt1000 or 22k NTC RTDs built
into the sensor.
SECURITY ACCESS CODES: Two levels of security
access are available. Program one access code for
routine calibration and hold of current outputs; program
another access code for all menus and functions.

4-Electrode Conductivity:
The Model 1056 is compatible with Rosemount
Analytical 4-electrode Model 410VP in the PUR-SENSE
family of conductivity sensors. This sensor supports
a wide array of applications and is capable of measuring
a large range of conductivity with one geometric
configuration. Wired to the Model 1056, this sensor
can measure 2μS/cm to 300mS/cm with an accuracy of
4% of reading throughout the entire range.
