Information About F2-8AD4DA-2

The F2-8AD4DA-2 is an advanced Analog Combo Module designed by Facts Engineering, engineered to deliver high-performance analog signal processing for PLC systems. Falling under the category of PLCs/Machine Control and classified as a VDC Logic I/O Module, this device provides eight analog input channels and four analog output channels, making it an essential component for industrial control applications that require precise and reliable analog data acquisition and output.

The F2-8AD4DA-2 is built with an input impedance of 1 MΩ, ±5%, allowing it to effectively measure a wide range of analog signals without loading the input source. This high impedance is critical for maintaining the integrity of sensitive signal measurements, ensuring that the connected devices are not affected by the input circuitry of the module. Additionally, the module is designed to withstand a maximum continuous overload of ±100V, providing robustness and protection against unexpected voltage surges in the system. This overload protection enhances the durability of the module, making it suitable for environments where voltage transients may be present.

To ensure accurate signal filtering, the F2-8AD4DA-2 employs active low-pass filters with a -3 dB point at 80Hz. This filtering capability helps eliminate high-frequency noise from the input signals, ensuring that the processed data is clean and stable. This is especially important in industrial environments where electrical noise is common and can interfere with the accuracy of analog signal measurements. The inclusion of active filtering makes this module a reliable choice for precision analog signal processing tasks.

The PLC input update rate for the F2-8AD4DA-2 is designed for efficiency, allowing the module to scan all eight input channels per cycle, with the maximum update rate achieved using pointers in a local base configuration. This fast update rate ensures real-time signal monitoring, which is essential for applications that require continuous data acquisition, such as temperature control, pressure monitoring, or motor speed regulation. By supporting rapid data updates, the module ensures that the control system can respond quickly to changing input conditions, maintaining system stability and accuracy.

The sample duration times for the F2-8AD4DA-2 vary depending on the resolution selected. At 12-bit resolution, the sample time is 2ms, while at 14-bit it is 5.52ms, and at 16-bit, it extends to 23ms. This flexibility in sampling duration allows the user to balance the speed of data acquisition with the desired level of resolution and accuracy. The oversampling successive approximation conversion method used by the module ensures that the input signals are sampled and converted into high-quality digital data, minimizing quantization errors and providing accurate representation of the analog signals.

The F2-8AD4DA-2 is highly accurate, with an inaccuracy rating of 0.1% of the range, which ensures precise data acquisition across a wide input range. Additionally, its input stability and repeatability are rated at ±0.03% of range after a 30-minute warm-up period, ensuring consistent performance once the system reaches operational temperature. The module also features exceptional accuracy relative to temperature, with a maximum drift of 25 ppm per degree Celsius. This low temperature coefficient ensures that the module maintains high accuracy even in environments with fluctuating temperatures, making it reliable for long-term use in industrial settings.

Calibration is critical for maintaining accuracy over time, and the F2-8AD4DA-2 offers a full-scale calibration error of ±0.07% of the range maximum, and an offset calibration error of ±0.025% of the range maximum. These low calibration errors ensure that the module performs consistently within its specified range, minimizing drift and maintaining precision over time. This makes it a dependable solution for applications that require long-term accuracy, such as industrial automation, process control, and data acquisition.

The F2-8AD4DA-2 also features excellent signal isolation and noise rejection capabilities, with a common mode rejection ratio (CMRR) of -90 dB at DC and -150 dB at 50/60Hz. This high level of noise rejection ensures that the module can effectively filter out interference from common mode signals, maintaining the integrity of the analog inputs even in noisy environments. Additionally, the module offers low crosstalk, rated at ±0.025% of range maximum at DC and 50/60Hz, ensuring that signals on one channel do not interfere with signals on adjacent channels. This feature is essential for multi-channel systems where signal isolation is critical for accurate data acquisition.

In summary, the F2-8AD4DA-2 Analog Combo Module from Facts Engineering is a robust, high-performance solution for industrial applications that require precise analog input and output processing. With its flexible input/output configuration, high impedance, advanced filtering, rapid update rates, and exceptional accuracy, the module is well-suited for a wide range of industrial automation and process control applications. Its durability, noise rejection, and low calibration errors further enhance its reliability, making it an ideal choice for environments that demand long-term accuracy and stability in analog signal processing.
