Rosemount 1056 Dual-Input Intelligent Analyzer
Features and Applications
The Rosemount 1056 dual-input analyzer offers single or dualsensor 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 Rosemount 1056 is powered. The instrument autorecognizes
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.The 1056 HART units communicate with the 375 HART®handheld communicator and HART hosts, such as AMS Intelligent Device Manager. Thel 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 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 Rosemount 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 panelmount, pipemount, and surface/wallmount 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.
Current Outputs
Two 4–20 mA or 0–20 mA current outputs are electrically isolated. Outputs are fully scalable and can be programmed to linear or logarithmic modes. Output dampening can be enabled with time constants from 0 to 999 seconds. Output 1 includes digital signal 4–20 mA superimposed HART® (option HT only).
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.
Information about each condition
is quickly accessible by pressing
DIAG on the keypad. User help
screens are displayed for most
fault and warning conditions to
assist in trouble shooting.
Display
The highcontrast LCD provides live measurement readouts in large digits and shows up to four additional process variables or diagnostic parameters. The display is backlit and the format can be customized to meet user requirements.
Local Languages
Rosemount extends its worldwide reach by offering seven local languages – English, French, German, Italian, Spanish,
Portuguese, and Chinese. Every unit includes user programming menus; calibration routines; faults and warnings; and user help screens in all seven languages. The displayed language can be easily set and changed using the menus.
