DR130 PORTABLE HYBRID RECORDER (DISCONTINUED)
A recorder's performance is determined by the readability of the information on its printed chart. The DR130 can record clearly, in 10 colors, data from all measurement points, at 2-second intervals. It has a variety of recording functions including analog trend recording over an effective recording width of 150 mm, recording of digital measured values, recording of various messages, zone recording, and partially compressed and expanded recording, thus enabling data to be read off speedily.
- Weighs only 9.3 kg.
- Measurement intervals: Max. 2 seconds
- Mutually isolated channels, and universal inputs
- Number of input channels; 10 channels or 20 channels (specify when ordering)
- Kinds of inputs: Universal inputs (DCV, TC, RTD, DI) or DCV/TC/DI dedicated inputs (specify when ordering), power monitor input options
- Effective recording width: 150 mm
- Memory devices: 3.5-inch floppy disk drive
- A wealth of PC-based application software
- DC power supply operation (optional) Recording example
Records clearly in 10 colors. You can assign a recording color to each channel.
Measured values are recorded digitally either at an interval based on the chart speed or at an interval that you specify. You can also start recording of data by a remote contact input.
By pressing a key, you can interrupt analog recording and digitally record one scan's worth of measured values.
The recording scale is printed out for each channel.
A change of the alarm status (ON/OFF state and time, for each channel) is printed out.
The contents of a preset message are printed out by pressing a key, when an input is received from a remote contact, or when an alarm is detected. You can preset up to 20 messages of 16 characters each
Headers are printed as comments (five rows of 60 characters).
Printing channel No. and tag No.
The channel number or tag No. are printed periodically.
You can freely set a wide range of inputs including DC voltage, thermocouple, RTD, and contact signals, by a simple key operation. A lineup of high cost performance models designed exclusively for voltage, thermocouple and contact inputs is also available. In addition, you can select power monitor input options that enable you to measure RMS values of AC voltage and current, active power, apparent power, reactive power, frequency, power factor and phase angle (for both single phase and 3-phase applications).

Mutual channel isolation. Reliable high withstand voltage and noise immunity
Each channel of the input circuit is isolated from the others by high breakdown voltage solid state relays*1 . As a result, the common mode rejection voltage is 250 V AC*2 rms, and the withstand voltage is 1,500 V AC*2 (1 minute). Excellent noise rejection is ensured by the built-in power line noise rejection filter employing an integrating type A/D converter, low-pass filter, and moving average digital filter*3.
*1: RTD inputs share a common line within the same module.
*2: Depends on input module types.
*3: The shortest measurement interval varies depending upon the integration mode and the low-pass filter mode.
Computation Function (partially optional)
The DR130 can perform various computations such as the four arithmetic operations, measurement data integra-tion processing, and detection of maximum and mini-mum values, in realtime. The results of computations are sent together with the measurement data to a PC thus reducing the burden of analysis work and improving the measurement efficiency.
The main computation functions of the DR130 are as follows.
Standard computation functions:
Linear scaling, moving average, differential computation
Four arithmetic operations, logic operations, related operations, computation of absolute and relative values, and statistical computations (maximum, minimum, mean, and integrated values)
Moving average function
This function renews the measured value while computing the moving average, hence it is effective for monitoring the trend of a varying input signal over a long period. It can also be used as a digital filter when noise components are present on the input signal. You can set the number of moving average scans by selecting a value between 2 and 64.
By using the DR130 in combination with the optional DI/DO module or alarm function, you can easily perform batch processing.
You can select a floppy disk function as an external memory device. You can save a number of set values and recall them whenever necessary, and in addition store the measurement data before and after an alarm, and also computed results. You can record the memorized data on a chart, or analyze it or make it into a report using a personal computer and commercially available spreadsheet software.
- If the floppy disk drive function is selected, the measurement data is stored in a binary format in the 512 kB (SRAM) internal buffer memory. You can also copy measurement data from the internal buffer memory to a floppy disk while converting it into the ASCII format.
- By combining the memory function with a remote function, timer, key operation, etc., you can memorize data at fixed intervals (e.g. 1 hour), or save the results of statistical computations alone (integrated value or maximum and minimum values).
- The DR130 comes with standard data conversion software, enabling you to convert data into the ASCII, Excel, or Lotus 1-2-3 format.
Other Standard Functions
|Input||Integration Mode Selection||
You can select the 50/60 Hz or 10 Hz integration mode. The 10 Hz integration mode is useful when power line noise containing both 50 Hz and 60 Hz components is superimposed on the signal. (When the 10 Hz integration mode is activated, the minimum measurement interval is 4 seconds.)
You can insert a low-pass filter in the path of a signal on which noise components are superimposed. (When the hard filter is ON, the measurement interval becomes at least 3 seconds.)
The input signal is displayed and/or recorded as an industrial quantity or a physical quantity.
When the thermocouple input goes open circuit, the indicator mores to the 100% or 0% side.
The difference between the reference channel and measured channel is measured.
||The recording area can be set freely for each channel.|
|Partially Compressed and Explanded Recording||Unimportant parts are compressed, and only necessary parts are expanded, thus enabling the recording resolution to be increased.|
|Group Channel Tred||Only channels that belong to a specified group are recorded. Switchover between groups can be done
using a remote contact.
|Alarm Generation Channel Trend||Trend recording takes place only for channels that emit an alarm.|
||The set data is protected by a lithium battery inside the unit.|
|Security||The unit comes with a standard password lock function, preventing mis-operation and also protecting the set data.|
|Alarm (Output is Optional)
||Setting||You can set a 4-level alarm (upper and lower limits, difference between upper and lower limits, percentage change rising and falling limits) for each channel.|
|Rebreakdown re-alarm||The alarm output can be refreshed when an alarm is emitted.|
|Hold Function||Once an alarm is emitted, the alarm indication and relay state are held until the operator acknowledges the alarm.|
|Option Functions||General purpose communication function (GP-IB, RS-232-C, Ethernet) and alarm output relay (10 make contacts)
DI/DO functions (recorder action control function, fail function, chart end function), etc.
|Conformity to Standards (based on)
||When the thermocouple input goes open circuit, the indicator mores to the 100% or 0% side.
