The Rosemount Analytical Model 56 Dual Input Analyzer is a line powered analyzer that offers single or dual sensor input with an unrestricted choice of dual measurement combinations. The device is offered in 24VDC or 115/230 auto-switching AC versions and includes two isolated inputs, four 4-20mA current outputs and four high load alarm relays. HART digital communications is a standard feature. Model 56 measures pH, ORP, ISE, Conductivity, Chlorine, Dissolved and Gaseous Oxygen, Dissolved Ozone, Temperature, Turbidity, or Flow and will accept 4-20mA current input. The unit supports SMART pH sensors from by Rosemount Analytical. All configurations meet UL approval requirements for Ordinary Locations.
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.
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.
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.
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.
Rosemount Analytical extends its worldwide reach by offering nine menu languages – English, French, German, Italian, Spanish, Portuguese, Chinese, Russian and Polish. Every unitincludes user programmingmenus; calibration routines; and faults and warnings in all nine languages.
Slide-in measurement boards allow easy sensor wiring and configuration changes in the field. There are no limitations for measurement or communication configurations.
Two levels of security access are available. Program one access code for routine maintenance and hold of current outputs; programanother access code for all configuration menus and functions.
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.
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.
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.
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.
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. Upload and download analyzer configuration to copy all programming settings on newly commissioned analyzers. Upgrade instrument software via USB.
All four current outputs 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. Transport Time can be used for PID control in a process liquid flowing in a pipe for a short period of time.
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. Fail safe operation and programming of relay default state (normally open or normally closed) is software selectable.
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.
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.
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.
