Product Description

The F3AD08-4W is a high-speed analog-to-digital conversion module specifically developed for the Yokogawa FA-M3 (Range-free multi-controller) platform. Featuring 8 independent differential input channels, this module captures precise current signals from field transmitters with minimal noise interference.

The F3AD08-4W (Model: F3AD08-4W) utilizes a 12-bit A/D converter to deliver a maximum resolution of 5.6 µA, making it essential for fine-tuned process control and industrial monitoring. Built for demanding factory automation environments, it incorporates photocoupler isolation to protect the internal PLC backplane from field-side electrical surges. Its differential input design provides superior common-mode rejection, ensuring data integrity even in electrically noisy settings.

The module is equipped with a standard 18-point terminal block using M3.5 screws, facilitating secure and straightforward wiring for 0–20 mA and 4–20 mA current loops.

Technical Specifications

Application Scenarios

The F3AD08-4W is primarily utilized in high-speed manufacturing sectors such as semiconductor assembly, pharmaceutical packaging, and food processing.

It is ideally suited for monitoring flow rates, pressure levels, and chemical concentrations where differential signaling is required to mitigate grounding issues or electromagnetic interference (EMI) across long cable runs.

FAQ

Can the F3AD08-4W measure voltage signals directly?
No, the F3AD08-4W is specifically calibrated for current (mA) inputs. For voltage measurements (e.g., 0–10 V or 1–5 V), please refer to the F3AD08-1V or similar voltage-specific modules in the FA-M3 series.

Is the terminal block included with the module?
Yes, the F3AD08-4W typically ships with its standard 18-point M3.5 screw terminal block. Replacement terminal blocks can also be ordered separately if needed.
