The F3AD08-5R (F3AD08) is a high-density, high-resolution analog-to-digital (A/D) conversion module for the Yokogawa Electric Corporation FA-M3 (Range-free Multi-controller) system. It provides eight channels of isolated analog inputs, designed for fast, accurate measurement of field signals in high-speed machine control, complex process monitoring, and industrial automation applications.
Featuring advanced noise-filtering and high-speed conversion circuitry, the F3AD08-5R allows the CPU to process sensor data with minimal latency. Each channel is individually configurable to support mixed signal types, and the module’s rugged design ensures long-term reliability in electrically noisy industrial environments.

Scaling Function: Converts raw digital values to engineering units, reducing CPU computational load.
Filtering Options: Digital filters and mean-value processing stabilize readings from sensors affected by high-frequency noise.
Peak-Hold Capability: Captures maximum and minimum values over a defined period for transient analysis.
Self-Diagnostics: Detects input wire breakage and internal hardware faults, reporting errors to system status registers.
Does the F3AD08-5R support current inputs like 4–20 mA?
The module is primarily voltage-input. Current signals can be measured using an external precision shunt resistor (typically 250 Ω for 4–20 mA) to convert current into a 1–5 V voltage signal.
What does the "-5R" suffix indicate?
The "-5R" designation identifies a high-speed, high-resolution revision of the FA-M3 analog module, offering 16-bit precision compared to standard 12-bit versions.
