YOKOGAWA AAM11-S2 is an analog input module launched by Yokogawa Electric, mainly used in industrial automation control systems. The detailed information is as follows:
- Brand: YOKOGAWA (Yokogawa Electric)
- Place of Origin: Japan
- Type: Analog input module
- Dimensions: Approximately 16.5cm × 6cm × 1cm
- Weight: Approximately 0.08kg
- Input Channels: Equipped with 8 analog input channels, supporting simultaneous acquisition of multiple groups of analog signals to meet the demand for multi-point parameter monitoring in industrial scenarios.
- Measurement Range: Capable of measuring voltage signals ranging from -10V to +10V, covering common voltage-type analog signals in industrial fields (e.g., signals from voltage-output temperature sensors, pressure sensors) and adapting to diverse analog input requirements.
- Sampling Rate: Features a sampling rate of 10kHz, enabling rapid capture of analog signal changes. This high sampling rate ensures timely reflection of transient signal fluctuations (e.g., sudden voltage variations in industrial processes) and provides real-time data support for the upper-level control system.
- Anti-Interference Capability: Possesses excellent noise resistance, allowing stable operation in complex industrial electromagnetic environments (e.g., areas with strong radiation from frequency converters or motors). It effectively suppresses electromagnetic interference to ensure measurement accuracy is not compromised.
- Installation Method: Adopts a simple plug-and-play design for easy installation. With its compact size and light weight, it can be effortlessly installed in space-constrained locations (e.g., small control cabinets or dense equipment racks).
- Compatibility: Compatible with a variety of Yokogawa Electric products, enabling flexible integration into different industrial control systems without extensive modifications, thus improving system expansion and upgrade efficiency.
This module is designed to receive and calculate contact pulses, voltage pulses, and current pulses from on-site equipment. It converts the input signals into isolated transistor contact pulses, which are then output as auxiliary signals. In addition, it can provide an auxiliary voltage output of 1-5V DC through the CN1 connector on the AMN11 socket, which can be used by recorders and analog I/O modules to supply power or transmit auxiliary signals for associated devices.
- High Precision: Achieves an accuracy of 0.5% under normal flow conditions, minimizing measurement errors and ensuring the reliability of measurement results for critical process parameters (e.g., flow rate monitoring in fluid transmission pipelines).
- High Reliability: Complies with SIL2 safety requirements, featuring high safety performance and reliability. It can be applied in scenarios with strict safety demands (e.g., chemical reaction processes, hazardous material handling systems) to reduce safety risks caused by equipment failures.
- Strong Anti-Interference: Adopts the "dual-frequency excitation method", which combines the stability of flow measurement under low-frequency excitation and the high noise resistance under high-frequency excitation. This method effectively resists interference from fluid working condition fluctuations (e.g., sudden changes in fluid pressure, flow rate) and electrical noise, ensuring stable and accurate signal measurement even in harsh working environments.
