Manufactured for high-performance industrial environments, this module provides reliable data acquisition from analog sources. It is categorized under PLCs and machine control, specifically as a PLC Module/Rack, and is used in automation systems that require precise analog input control. The F2-04AD-1 is equipped with four single-ended analog input channels, allowing it to collect input signals from various sources, such as sensors and transmitters. These signals are processed through a 4–20 mA current range, which is commonly used in industrial control systems for reliable and noise-resistant signal transmission. The input range is optimal for monitoring process variables such as pressure, temperature, or flow rate in critical control applications. The module offers a resolution of 12 bits, equivalent to 1 part in 4096, enabling accurate and detailed signal processing. This level of resolution ensures that the module can capture small changes in the input signal, which is essential in applications that require precise measurements for process control and monitoring. The step response of the F2-04AD-1 is 4.9 milliseconds, with the ability to reach 95% of the full step change in approximately 4.0 milliseconds. This fast response time ensures that the module can quickly adapt to changes in the input signal, making it suitable for applications that require real-time monitoring and control. The unit's crosstalk is rated at -80 dB, with a maximum deviation of 1/2 count, ensuring minimal interference between channels, which is essential for maintaining the integrity of multiple signals being processed simultaneously. The module features active low-pass filtering, with a cutoff frequency of -3 dB at 120Hz (or 80Hz), with two poles providing attenuation of -12 dB per octave. This filtering helps reduce high-frequency noise in the input signal, ensuring clean and accurate data acquisition, especially in environments with significant electromagnetic interference. Input impedance for the F2-04AD-1 is 250Ω ±0.1% with a 1/2 watt rating for current input, ensuring stable and accurate signal measurement. The module can handle absolute maximum ratings of ±40mA for current input, providing tolerance for transient signal fluctuations without damaging the unit. The converter type used in this module is a successive approximation analog-to-digital converter (ADC), known for its accuracy and fast conversion times, making it ideal for industrial applications where both speed and precision are required. In terms of performance, the F2-04AD-1 ensures accurate signal conversion, with a linearity error (end-to-end) of ±1 count, or 0.025% of full scale, ensuring high precision across its entire input range. The module is also designed with input stability in mind, maintaining a stability of ±1 count, further reinforcing its reliability in critical applications. Calibration accuracy is a key consideration for this analog input module. The full scale calibration error is ±12 counts maximum at 20mA input, while the offset calibration error is ±7 counts maximum at 4mA input. These calibration tolerances ensure that the module remains accurate across varying signal ranges, which is essential in maintaining control precision in industrial processes. The F2-04AD-1 is designed to operate in a wide range of environmental conditions. Its operating temperature range spans from 0°C to 60°C (32°F to 140°F), allowing it to function effectively in typical industrial environments. For storage, the module can withstand temperatures from -20°C to 70°C (-4°F to 158°F), ensuring durability during transportation or non-operational periods. The module is designed to operate in relative humidity levels between 5% and 95%, non-condensing, making it suitable for environments with variable humidity. In terms of environmental air requirements, the module must be used in environments free from corrosive gases, as exposure to such conditions could degrade its performance and longevity. The module meets military-grade standards for vibration and shock resistance, including MIL STD 810C 514.2 for vibration and MIL STD 810C 516.2 for shock. This ensures that the module can withstand the physical stresses commonly encountered in industrial settings. Furthermore, the F2-04AD-1 is equipped with noise immunity protection in accordance with NEMA ICS3-304 standards, allowing it to maintain performance in electrically noisy environments. In summary, the F2-04AD-1 analog input module is a robust and high-precision solution for data acquisition in industrial control systems. Its four input channels, high resolution, fast response time, and noise-resistant features make it an excellent choice for a wide range of automation applications, from process monitoring to control system integration. Its durable design and adherence to industrial and military standards ensure long-term reliability in demanding environments.
