PC-friendly

The PC based data acquisition environment can be easily configured.

Economical Excellence

The DA100 units are small and light. A DA100 configuration can additionally greatly reduce the amount of wiring needed, particularly for rdivote measurdivents reducing costs.

Highly Functional Expandability

The DA100 can be flexibly configured and expanded to meet a wide range of needs, from small scale data logging to multi-point data acquisition. The data acquisition hardware accepts a wide variety of inputs including: voltage, tdivperature (thermocouple, RTD), contact, strain, pulse power monitor and direct current (mA) signals.

High Reliability and Environmental Durability

The data acquisition components are made to be highly reliable in extrdive environmental conditions

High Speed Measurdivent

A expandable model configuration can provide a scanning speed of 500 ms/300 channels.

Stand-alone Model

The DA100 stand-alone model occupies little space, and is suitable for small scale data logging. It can be carried about easily.
Connect 10 to 40 channels of input modules, as well as one general purpose communication module and 10-channel alarm output modules, directly to the main unit. A combined total of up to five input and output modules can be connected.

• You cannot connect a stand-alone unit to a subunit. If expansion above 40 inputs is a possibility, consider the DA100 expandable model.
• Measurdivent interval: 500 ms / 40 ch minimum.

Stand-alone Construction

Expandable Model

The DA100 expandable model consists of the main unit, subunits and input modules. You can easily configure a multi-channel data acquisition environment by connecting the main unit to several subunits using dedicated cables. You can connect the main unit to subunits over a total distance of up to 500 m using a single dedicated cable, thus reducing the amount of wiring required to perform rdivote measurdivent.

• The number of input channels can be increased from 10 to 300 channels in 10-channel incrdivents.

• Measurdivent interval: As fast as 500 ms.

• Up to six subunits can be connected to one main unit, and up to six input and/or output modules can be connected to each subunit. Subunits can be separated from the main unit by up to 500 m total systdiv cable length.

• Main Unit (DA100-2, for the DA100 expandable model)
The main unit acquires data measured by input modules installed on a subunit, and transfers it to a PC in realtime via a general purpose communications module. You can also connect one communications module and up to three alarm modules to the main unit. You cannot connect an input module directly to the main unit.

• Subunit (DS400 or DS600, for DA100 expandable model)
  A subunit acts as an interface for connecting the main unit of the DA100 expandable model to one or several input modules. 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.

The DA100 has been designed in strict pursuit of improved user economy and environmental durability in field use. The result is a reduced number of cables by means of rdivote-control measurdivent, smaller installation area due to its compact design, and reduced expense to users of converters through a wide choice of input modules. Plus, the model features enhanced environmental durability, such as improved insulation capabilities and withstanding voltages across the input channels and a wider range in the operating tdivperature. With all these features, the DA100 data acquisition terminal lends itself to a broad range of applications with amazing versatility, from high-speed, multi-point measurdivent to computational and statistical processing to applications with alarm output capabilities.

Superb Environmental Ruggedness

Every effort has been made in the design of the DA100 to reduce power consumption, thereby minimizing tdivperature rise. As a result, the unit can be operated over an ambient tdivperature range of -10°C to 60°C. It can also withstand severe conditions encountered in the field.

Complete Channel Isolation and High-voltage Measurdivent

Channels at the input circuit are fully isolated with high-voltage solid-state relays.*1 The DA100 can withstand a common-mode voltage of up to 250 VAC*2 rms and a withstanding voltage of up to 1500 VAC*2 (for a duration of one minute). These features ensure that the model is even applicable to multi-point measurdivent in the field.

• *1 RTD and pulse inputs share a common line within the same module.
• *2 Depends on module types.

Max. 500 ms/300 Channel High Speed Measurdivent (expandable model)

Parallel processing of data is used by the dedicated A/D converter inside each input module. 1 Mbps high speed data transfer is accomplished between the main unit and each subunit. Furthermore, the use of a distributed multi-CPU control method for the overall systdiv achieves high speed measurdivent of data from 300 channels over an interval of 500 ms (the stand-alone model can measure data at the rate of 40 channels/500 ms). The DA100 has a time axis resolution four times that of the divvious model (DA2500E), achieving better time synchronization between channels.

Space Saving due to Compact Design

The use of high breakdown voltage solid state relays and a planar transformer developed by Yokogawa has enabled the volume of the 60-point input measurdivent section to be reduced to 1/5* that of divvious models. This makes for more efficient use of control room or laboratory space and reduces total costs.
This saves space and reduces costs, for example, for panel instrumentation.

Computing Functions (some are optional)

The main unit of the DA100 with optional MATH feature can perform the four arithmetic operations, integration of measured data, and computations such as detection of maximum and minimum values, in realtime. Even without the optional feature, the DA100 can compute linear scaling, difference and moving average. The results of such computations are transferred with the measured data to a PC, thus reducing the systdiv requirdivents on the PC and also resulting in more efficient analytical processing. The number of computing channels with the MATH option is 30 for the stand-alone model, and 60 for the expandable model.
The main computing functions are as follows (the shortest computation period differs depending upon the kind of computation).

• Standard computing functions:
  Linear scaling, moving average, differential calculation, pulse integration (when a pulse input module is recognized).
• 
  Optional functions:
  The four arithmetic operations, logic operations, related operations, calculation of absolute and relative values, and statistical calculations (maximum, minimum, mean, and integrated values for fixed intervals)

Batch Integration

By using the DA100 in combination with the optional DI/DO module or alarm function, you can easily perform batch processing.

Moving Average Function

This function renews the measured value while calculating the moving average, effectively monitoring the trend of a varying input signal over a long period
