  For analog trend mode + digital printing, chart speed of 25 mm/h, and a scan interval of Auto, it is approximately 6 months. In logging mode with a recording interval of 1 hr, it is approximately 2 months. This is the same for the DR231 ...
The maximum number of channels is 145 when channel numbers are set, and 87 when tag numbers are set. <Conditions> Logging interval = 1 min., single loop mode Alarm setting: None, MATH setting: None (both standard and MATH option disabled) The l...
The DR230 is part number B9627AY (25 mm). The DR130 is part number B96855AY (10 mm).
It is a lithium battery with a 10 year life (at an ambient temperature of 23°C, under normal operating conditions).
It takes approximately 70 seconds to copy the data in RAM (512 KB) to a floppy disk.
Data loaded onto floppies also includes the date/time of measurement, but when you reopen it, the date/time of reopening is recorded.
The following voltages can be applied. Ground potential: 350 VDC (common mode noise voltage 250 VACrms × 1.1414). Between ch: 200 VDC (max. noise voltage between channels 150 Vrms × 1.1414). Between channels means the voltage between chan...
No. The DR's recording interval is 2 seconds. If the scan interval is 0.5 seconds, 3 data measured from one recording to the next would be thinned. If 1 second, 1 data would be left out.
You can set digital printout for each channel. If you turn digital printout of all channels OFF, digital printout stops, including the date.
The current data is not necessarily printed when the manual printout is started. With data that is manually printed, 1 scan's worth of data is held every scan. When a manual printout is requested, that 1 scan's worth of data is sent, and prin...
When does the DR scale printout occur?
(ns-faq-darwin-8038-spec)
The DR's scale printout format can be selected for each channel as OFF, ON1, ON2, or ON3 (OFF means no printing). Also, the DR can accept mixed input, so the scale printout for each channel might differ. If so, the scale is printed out starting f...
When creating a data file in memory (512 KB RAM), files are added without overwriting until the memory is full. Therefore if the set data length is longer than the remaining memory, the setting can no longer be entered. Check the amount of memory whe...
There is no strict specification for the input current value of DCV/TC INPUT, but the current value can be determined from the following specification. DCV/TC INPUT specification Max input voltage: V 2 VDC range, thermocouple, RTD: ±10...
You can, starting with style 8 of the DA. Setting command: VS. Control execute command: VD. The DR and DC do not support this. With DAQ32 and DAQ32Plus you can set up output relays, but you can't actually operate them with commands. You can also ...
The voltage generated when a burnout current of 4.2 mA flows to the measuring terminal circuit is measured in the 60 mV range, and a determination is made. If 42 mV (10 kΩ) or more, the result is 0 (open). If less than that, 1 (closed).
For 0.5 second models, temperature is measured for RJC every 2.5 seconds (with a 0.5 second scan, since the time for processing temperature measurement, burnout, and other factors is too short, measurement occurs every 5 cycles). For 2.0 second mode...
Is there a limit on the extender modules?
(ns-faq-darwin-8052-select)
Extender modules can be connected to the main unit (DA100-1) and subunit (DS400, DS600). However, only 1 extender module can be connected to each. Total cable length: expansion cable (max. 500 m) + extender cable (max. 30 m). Even if using an extende...
Yes. The integral value is the scale calculation.
On the RS232C communication module, set communication parameters by using the dip switches on the front of the module. Make sure the communication module’s dip switches match what is displayed on the DAQ32's “Environment, diagnosis, a...
No, on DARWIN, only a vertical parity check is performed.
The range of the strain input module depends on the measurement mode and gauge method. (see the table below) Meausrement mode 2K 20K 200K 1 gauge method -2000 to +2000µε -20000 to +20000µε...
Unless you set the counter to go back to zero with the SETUP function, an overflow results.
Overview:

Unless you set the counter to go back to zero with the SETUP function, an overflow results.

This requires upgrading the DARWIN hardware style. Please submit for factory rework.
Generally they are not initialized if the modules are not different from the previous system. However, initialization happens if slots are in the following conditions. Slot replaced with a module of a different model name or style number Slot who...
  When measuring strain with initial balancing (EXEC), measurement is performed using the state with the gauge connected as a reference criterion. Therefore, you must balance the bridge with the gauge connected. This balancing is called initi...
  RELATIVE: Count begins from the moment the timer time is set, and timeup occurs when a set time is reached. For example, if timer 1 is currently at 7 days/10 hours/00 minutes, and you set 01 days/10 hours/00 minutes, the timeup occurs every...
After entering Setup mode settings (including burnout), you have to store the settings using the XE command. If you don't send the XE command, the settings are ignored.
If you specify unidentified channels, no errors occur but the channels are ignored.
When applying a moving average, the decimal places matches the number of digits in the range.
4.2 µA flows from a burnout power supply, resistance is measured, and the determination is made. : Thermocouple is normal: Less than 10 KΩ Thermocouple breaks, and while it is breaking: 10 KΩ or more
The input types are non-voltage contact and open collector. Hence, it is not necessary to input a voltage to pulse input. This specification shows the withstand voltage and current capacity determined for contacts or transducers. In other words, a co...
Yes. Set the IP address, subnet mask, and default gateway on the main unit.
DAQ32 (DP120) or DAQWORX DAQ32 Plus (WX102) installed on Windows 7 or Windows Vista cannot change the IP address of DARWIN series Ethernet modules (suffix code /C7) or DARWIN series standalone models with the Ethernet communications option (model cod...
Does DARWIN support Windows XP?
(ns-faq-darwin-8017-spec)
R10.03 and later support Windows XP.
For voltage measurement, if 5% of range + range span is exceeded, an overrange occurs (±32767 is output). For temperature range, the +10°C measuring range is the upper limit. Ex) For the ±50 V range (span of -50 to +50), the upper l...
Thermocouple data is generally not included with our digital devices. The accuracy of data measured with thermocouples is the combined accuracies of: the thermocouple itself; the temperature compensator; the linearization that approximates the thermo...
The Viewer cannot determine the numbers after the decimal with statistical computation on DI input. Data acquired and results computed by the BFD32 are affected by the decimal of the specified measurement range. For DI (contact input), a 4.2 µA...
