ASSY DATA TRANSLATION CONTROL BOARD 918-0401 REV.B ANALOG DEVICE AD210JN

This item is an ASSY (Assembly), specifically a Data Acquisition (DAQ) Control Board or Interface Card manufactured by Data Translation. It is a specialized printed circuit board (PCB) designed to be the core component of a larger data acquisition system, likely a external box or a proprietary industrial computer.

The key component on this board is the Analog Devices AD210JN, which is a high-performance, 3-Port Isolation Amplifier.

Key Components & Specifications

• Manufacturer: Data Translation (A well-known and respected manufacturer of data acquisition hardware and software, founded in the 1970s and later acquired by various entities including Analog Devices).

• Part Number: 918-0401 REV.B – This is the specific assembly number for this control board. “Rev.B” indicates it is the second revision of the board, containing minor fixes or improvements over the original.

• Critical Component: Analog Devices AD210JN Isolation Amplifier. This chip is the heart of the board’s functionality.

  • Function: It provides complete electrical isolation (typically 2500V or more) between the input signals, the output signals, and the power supply. This is absolutely critical in industrial environments to:

    1. Protect expensive computer equipment from voltage spikes, noise, and ground loops coming from factory machinery.

    2. Ensure accurate readings of small sensor signals by blocking interference.

    3. Protect operators from high voltages.

  • 3-Port: It isolates the input, the output, and the power, each from one another.

• Primary Function: This board almost certainly functions as a multi-channel isolated analog input module. It would take real-world analog signals (e.g., from thermocouples, pressure transducers, strain gauges), condition them, isolate them, and digitize them or prepare them for a computer’s bus (like ISA, PCI, or a proprietary connector).

What is it used for? (Purpose)

This board was designed for industrial data acquisition and process control. Its specific applications would include:

• Factory Automation: Monitoring temperatures, pressures, and forces on a production line.

• Test and Measurement Stands: Acquiring data from sensors in automotive, aerospace, or product testing environments.

• SCADA Systems: Supervisory Control and Data Acquisition in industries like water treatment, oil & gas, and manufacturing.

• Laboratory Instrumentation: Isolating sensitive measuring equipment from noisy power sources.

Who is this for? (Ideal User)

This is a highly specialized, legacy industrial component for a very specific user:

• Industrial Maintenance Technicians or Engineers who are responsible for maintaining very old, proprietary data acquisition systems that use this exact Data Translation assembly.

• Vintage Industrial Computer Collectors or Restorers.

• Someone with a broken Data Translation system (e.g., a DT800 series box) who needs this exact board for a direct replacement to get their critical system running again.

Critical Considerations for a “USED” Unit

1. Extreme Obsolescence: This is a legacy component from the 1980s or 1990s. It is not compatible with modern computers without the rest of the original system (e.g., a proprietary interface box and likely obsolete software drivers for DOS or old versions of Windows).

2. No Standalone Function: This is an assembly, not a complete product. It cannot be used by itself. It requires the specific chassis, power supply, and cabling it was designed for.

3. Unknown History: As a used board, its functionality is unknown. Capacitors age and can fail, and static discharge can damage sensitive components.

4. Documentation: To have any hope of using it, you would need the exact Technical Manual or Datasheet for the Data Translation product it came from.
