Details

Expandable Model

The DR230 expandable model enables you to start with a small number of channels, and conveniently expand, up to 300 channels. The architecture of the DR230 allows you to increase the number of input and/or output modules as your application needs change.
The versatility of the DR230 recorder enables you to freely configure a recording/data acquisition environment that matches your particular application, while effectively reducing your initial investment.

The DR230 expandable model consists of a main unit, subunits, input/output and communications modules. Connecting the main unit to multiple subunits with dedicated cable of up to 500 m total length, you can easily configure a recording/data acquisition environment ranging from 10 to 300 channels. Another key feature is its ability to scan up to 300 channels every 500 ms. You can also install one subunit on the back of the main unit of the hybrid recorder.

Main unit (DR232)

The DR232 acquires data measured by the input modules installed on each subunit, records the data in real time and/or transfers it to a PC using a general-purpose communications interface, and also stores it in a memory device.
You can connect a communication module, GP-IB, RS-232C or RS-422/485, and also a DI/DO module to the main unit. An input module, on a subunit (DS600), can be installed on the back of the main unit.

Subunits (DS400, DS600)

A subunit acts as an interface for connecting input modules to the main unit of the DR230 expandable model. There are two types of subunits, the DS400 which permits connection of up to four input and output modules, and the DS600 which permits connection of up to six input and output modules.
Normally, when a subunit is connected, it will be at a separate location from the main unit.
When a subunit DS600 is mounted on the back of a main unit, a dedicated cable is required between them.

You can with the following methods. If you short any channel of any module attached to the subunit (always 0 V in voltage measurement mode) and set an alarm and relay output on the channel, the alarm occurs constantly, and the alarm output relay turn...

Only the DS600 can be connected directly to the back of the DR242. The DS400 is too narrow, and cannot be connected. Use the DS600's standard accessory parts to make the connection. The DS600 is attached to the DR232 expandable model main unit in...
Check the DR230's main screen to see if RECORD, C, M, or T light up or appear. If any of them light up or appear, stop those operations. RECORD: Stop recording. C: Stop computation. Press the FUNC key, then select MATH STOP. M or T: Stop saving t...
Yes, as long as the style number of the communication module is less than or equal to that of the main unit. The style number is printed on the name plate of the main unit and communication module. The main unit's name plate is back behind the ch...
In principle, they should continue to run even if their upstream subunit has a power failure. However, temporal effects will be experienced (data acquisition will be temporarily lost, or certain data might become damaged).
It is a Yokogawa proprietary protocol that is HDLC compliant.
  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 ...

It is a lithium battery with a 10 year life (at an ambient temperature of 23°C, under normal operating conditions).
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...
Data loaded onto floppies also includes the date/time of measurement, but when you reopen it, the date/time of reopening is recorded.
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...
You can set digital printout for each channel. If you turn digital printout of all channels OFF, digital printout stops, including the date.
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.
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...
It takes approximately 70 seconds to copy the data in RAM (512 KB) to a floppy disk.
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...
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...

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 ...
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...
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).

No, on DARWIN, only a vertical parity check is performed.
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.
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.
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
  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...
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.
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...
