Model DA-07 -Remote Device Controller

The DA-07 communicates with the CIMScan server computer using the standard TCP/IP protocol over a Local Area Network (LAN) or the Internet. The unit has the ability to buffer up to 12.000 measurements if a LAN fault occurs or if the server fails for any reason. These measurements are automatically forwarded to the server when communications are restored.
The remote devices are sampled every 1 to 15 seconds depending on the number of channels that are in use. These measurements are averaged for the user-configurable sample rate. The normal server update rate can also be configured by the user as well as alarm limits for each channel. As long as the incoming measurements remain within the limits, the server is updated at the normal update rate. If, however, the limits are exceeded, the server update rate reverts to the sample rate (faster updates). Both the scan and server update rates can be configured by the user. It is often a requirement to have particle counts expressed in particles per cubic meter in addition to the normal particles per cubic foot The DA-07 easily handles this with a simple configuration setting. The DA-07 calculates the following statistics for every input channel and forwards them to the server at the end of every hour.

• Maximum detected during the hour
• Minimum detected during the hour
• Average over the hour (arithmetic mean)
• Aspecial calculation (variance, MKT. totals)

Every input channel can be field calibrated (scale and offset values provided). Aconvenient calibration dialog is available in the service tool program.

• Manages up to 16 Remote Devices (I/O Pods, sensors, instruments) for a total of 128 channels
• Automatically calculates statistics (max, min, average) and makes a special calculation (variance, MKT, totals, etc.) for each input channel
• Buffers up to 12,000 measurements during LAN or server outages
• Handles local alarm processing during LAN or server faults.
• Communicates with the server over a LAN or the Internet using TCP/IP
• Operates from a simple 10 to 30Vdc power supply (unregulated)
• Handles Vacuum Pump Control
• Small Size and Low Cost
