Yokogawa FX1006-4-3-L FX1000 Paperless Recorder

The Yokogawa FX1006-4-3-L, also cataloged as the FX1006 Data Acquisition/Recorder Module, operates as a dedicated hardware component for recording and displaying analog and digital signals from field instruments within process control topologies. The instrument executes direct physical acquisition across 6 universal input channels, digitizing raw voltage, current, and temperature sensor inputs via an internal 16-bit A/D conversion matrix. By maintaining distinct galvanic boundaries between input circuits, the unit logs high-resolution trend measurements directly to localized internal non-volatile memory and removable CompactFlash media.

Hardware Specifications

Process Control Instrumentation Interface & Logic Attributes

The multi-channel input stage implements programmable sensor terminations engineered to accept the 4-20 mA HART loop protocol when driven by external shunt resistors. Channel-to-channel isolation networks construct robust electrical partitions that inhibit high-voltage common-mode drift, stopping cross-channel telemetry errors during high-temperature measurement operations. For primary temperature tracking loops, integrated cold junction compensation (CJC) circuits dynamically correct thermoelectromotive drift directly at the copper screw terminals, processing raw thermocouple sensor inputs into linearized data streams for transmission over the network architecture.

Frequently Asked Questions

Q: How does the recording engine prevent data corruption if the primary 100-240 VAC power source fails unexpectedly?

A: The device automatically logs incoming data into non-volatile internal flash memory. This design structure prevents historical trends and operational parameters from being erased during blackouts, allowing the instrument to resume processing lines immediately upon power restoration.

Q: What action must a field technician execute to process standard 4-20 mA inputs on the universal termination board?

A: The universal input pins operate natively as high-impedance voltage terminals. To acquire standard 4-20 mA current loops, installers must bridge the positive and negative channel screws with an external 250 Ohm precision shunt resistor to scale the loop current into a proportional 1-5 VDC input signal.

Q: What electrical protection is provided by the specific -L suffix option when multi-channel inputs share a common wire way?

A: The -L suffix designates a reinforced galvanic isolation barrier capable of sustaining up to 400 VAC (50/60 Hz) between individual input terminal sets for 1 min. This hardware specification ensures that localized phase-to-ground short circuits on one sensor cable will not migrate into and destroy the processing electronics of the other five channels.

Field Installation Guidelines

• Enclosure Ground Setup: Bolt the recorder body securely into the panel cutout, verifying that the rear grounding screw links directly to the primary structural earth bus bar through a heavy-gauge copper wire to route high-frequency line noise away from the A/D converters.
• Drain Wire Shield Matrix: Terminate all incoming thermocouple and RTD instrument cable shields directly onto an external uninsulated ground plate. Do not allow bare shield wire strands to project into the active terminal strip connectors.
• Separation of Signal Conductors: Guide all low-voltage sensor cabling inside dedicated plastic wiring pathways, maintaining a strict minimum clearance space of 200 mm from high-amperage AC power supply conductors or electrical drive loops.
• Termination Screw Torque: Adjust all terminal strip retention screws to the specified manufacturer tightness limits to prevent micro-disconnections or thermal measurement shifts under conditions of regular industrial vibration.
