DR240 Expandable Model

DR240 expandable model
The DR240 expandable model consists of a main unit, subunits, input/output and com-munications modules. Connecting the main unit to multiple subunits with dedicated ca-bles of up to 500 m total length, you can easily configure a recording/data acquisi-tion environment ranging from 10 to 300channels. 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.
Subunits (DS400, DS600)
A subunit acts as an interface for connect-ing input modules to the main unit of the DR240 expandab
le 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 con-nection of up to six input and output mod-ules.
Normally, when a subunit is connected, it will be at a parate 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.)
Alarm output module
This is a 4-channel or 10-channel output module which outputs contact alarm signals according to pret conditions. You can t four alarm levels per channel (choo from upper limit, lower limit, delta high limit, delta low limit, or rate-of-change). You can install alarm output modules on the subunits.
Input Module
The input module is a 10-channel* small remote multiplexer that A/D-converts the measured signals as fast as every 500 ms.** The input signals include not only DC voltage and temper-ature, but also
contact, power monitor, pul, strain and DCA (mA) signals.
*:Power monitor modules are 2- or 6-channel.
**:If input modules of different measurement intervals are mixed, the resulting measurement interval is that of the longest interval
input module.
● Universal Input Module
The universal input module permits mea-surement of DC voltages between 20 mV and 50 V, thermocouple inputs, RTD inputs,and contact signals in up to 500-ms inter-vals.
Other cost-effective universal input modules are available that measure data from 20 or 30 channels in 2-cond intervals, and low-cost dedicated input modules that accept voltages and thermocouple outputs.● Strain Measurement Module
The strain measurement module measures static strain, and comes in two types.
One corporates a 120 or 350 Ω bridge resistor,the other is for connecting an external bridge box. One module enables data in 10 channels to be measured, however, it requires two slots worth of space.The minimum measurement in-terval (data update cycle) is 500 ms.● Pul Input Module
The pul input module receives TTL or con-tact signals from a flow or tachometer, and counts and integrates the number of puls-es. The minimum measurement interval is 0.5 cond and the data update cycle is one cond.
● Power Monitor Module
果多念什么
The power monitor module receives AC volt-age or current input signals and measures RMS values, active power, apparent pow-er, reactive power, frequency, power factor and pha angle.
The minimum measurement interval (data update cycle) is 2 conds.
Main unit (DR242)
The DR242 acquires data measured by the input modules installed on each subunit,records the data in real time and/or trans-fers it to a PC using a general-purpo com-munications interface, and also stores it in a memory device.
You can connect a communication module,Ethernet, RS -232C, RS -422/485 or GP-IB,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.

General-purpo communications module
You can connect a Ethernet, RS-422A/RS-485, RS -232C, or GP-IB general-purpo communications module to the back panel of the main unit. All measured data is trans-ferred in real time via the installed commu-nications module.
DI/DO module
This module enables the DR240 hybrid re-corder to be controlled* from a remote lo-
cation, and also outputs the chart end and recorder fail signals to your external annun-ciator.
*Remote control functions:
Start and stop recording Change chart speed Start message printing
Start and stop memory sampling Control statistical calculation interval想谈恋爱了
The DR242 expandable model incorporates the fail and chart end output as standard features.
● Direct Current (mA) Module
The shunt resistor (100 Ω) is pre-installed to measure the DCA signal.
Extension module
Using an extension module, you can sup-ply power directly from a subunit for each input module*1, mounted on an extension ba unit. Also, connecting an extension module on a subunit allows connection of up to three input modules as well as three extension ba units, over a distance of up to 30 m.

Ethernet Module
The Ethernet module enables you to achieve high-speed, multi-channel, remote data com-munication via Ethernet. The module supports all commands generally ud for DARWIN and permits data access from a max-imum of four personal comput-ers (configured to do so with ur-created software).

This model has a simple building block architec-ture, and comes with I/O and communications modul
es installed on the back of the main unit.
Structural Simplicity
DR240 Stand-alone Model
Specify 10, 20 or 30 input channels, and desired options, at the time of ordering.
Simple integrated construction
You can connect 10, 20 or 30 channels directly to the main unit.
The DR240 stand-alone model, which comes with I /O modules already in-stalled, is a cost-effective general-pur-po model.
The external appearance, recorder function, memory and communications functions of this model are identical to tho of the expandable model. Be-cau this model is of integrated con-struction, it can be carried about easily.
Universal and power monitor range
Universal inputs permit measurement of a variety of inputs including DC voltage,thermocouple, RTD and contact signals.Low-cost model for measuring only voltage and thermocouple signals is available. You can also lect power monitor (optional) for measuring AC voltage and current.
Variety of options, including gen-eral-purpo communications and DI/DO functions
General-purpo communications (Eth-ernet, RS-232C, RS-422A/485, and GP-IB), 10-point SPDT alarm output relays,DI /DO (2 alarm relays, remote control of recorder, CPU fail and chart end con-tacts).
Specify your required options when or-dering.

8Clear Hybrid Recording Functions
A recorder's performance is measured by the read-
ability of the information on its printed chart. The
DR240 can record clearly, in 10 colors, data from
all measurement points, at 2-cond intervals. It
has a wide variety of recording functions including传统节日的古诗>给领导送礼说什么
analog trend recording over an effective recording
width of 250 mm, recording of digital measured
values, recording of various messages, zone re-
cording, and partially compresd and expanded
recording, that help interpret the data.
● High speed recording at 2-cond intervals● Programable ten-color recording
● Versatile recording formats
The interpolation function enables data points of each channel to be linked by lateral line gments so
as to show the continuity of the data.
