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.
