Honeywell DR45AR Truline® Circular Chart Relay Expansion Recorder Agent

Function  The DR45AR Food/Pharmaceutical  and Relay Expansion Recorder  combines the broad capabilities of  Honeywell’s Truline recorders with the  special features needed to serve the  food and pharmaceutical industries.  These features include:  

• FO Calculation; or up to two  totalizers  

• 2, 4, or 6 alarm relays  

• up to 6 customer-configured messages activated by internal alarms  or digital inputs  

• 200-ohm Burns bulb actuation  

• Optional UL and FM approved  NEMA4X door available.  

• setpoint security with a four-digit  alphanumeric code configured by  the customer  Honeywell’s Model DR45AR Truline  recorder is a one to four-channel, ALM CHN RSP OUT 1 F 3IN 86.0 1559 % ruline 

20889 Figure 1—Truline recorder provides printed chart data and continuous  digital indication of process variable value.  microprocessor-based, circular chart  recorder. Its “one-pen” stylus  printhead produces up to four analog  traces and prints alphanumeric chart  data on a blank heat-sensitive chart.  All four traces share the same time  line reference, which the Truline prints.  This eliminates the error caused by  pen alignment offsets in conventional  pen designs.  Since the Truline prints the chart and  generates the analog traces at the  same time, there is no error due to  variations in chart size caused by  changes in temperature and humidity.  In addition to printing informative,  accurate chart records, the Truline  recorder alternately displays process  variable values for all channels in the  selected engineering units.  

Features  User Configurable — English  language prompts, coupled with  simple keystroke sequences, make  configuring the recorder easy and  straightforward. You can set and/or  alter operating parameters to fit your  requirements without re-calibration.  

Operator Interface — bright, vacuum  fluorescent, alphanumeric digital  displays make pasteurization process  data instantly available to your  operation.  

Bargraph Display — indicates  deviation of ± 10% of input span with  center bar, On-control with center bar,  On-control indication.  

All-Purpose Chart —One all purpose,  blank chart eliminates the need for  ordering and stocking several types of  charts. Users can design the chart to  match their specific application.  

Four Channels — monitor process  variables from a variety of sensor  types help reduce panel space  requirements  Features, continued Control Output — up to two versatile  PID controllers lets you configure the  exact control action needed for your  process.   

“One-pen” Printer — prints  configurable alphanumeric chart data  including time and trend lines. This  automatically compensates for chart  width variations caused by changes in  the ambient relative humidity.  

Time/Date — To guard against  unauthorized chart advancement, an  integral real-time clock provides  accurate timing for the recorder’s time  and date printing, and also any  operator changes. A 10-year life  battery backup assures correct timing  even when power fails.
