Data Sheet
Functional Features
Multi-Channel Design: The module is equipped with 16 analog input channels featuring differential input type, which effectively suppresses common-mode interference to ensure accurate signal acquisition in complex electromagnetic environments. This multi-channel design allows simultaneous connection to multiple external sensors or signal sources, greatly improving the efficiency and comprehensiveness of data collection. It is suitable for industrial systems requiring monitoring and control of multiple analog quantities, such as synchronous acquisition of temperature, pressure, and flow parameters in chemical production.
High Resolution & Precision: It boasts excellent analog input resolution with different count configurations for various input ranges. For example, the resolution reaches 0...4095 counts at 4-20mA input, and 0...25000 counts at 0...25mA input, etc. The absolute maximum input is 30mA, with an input impedance of 250 ohms. The absolute accuracy error is only ±0.125% of full scale, and the linearity error is controlled at a minimal value across different input ranges (e.g., ±6μA max at 4-20mA). Such high-precision signal acquisition capability makes the module excel in scenarios demanding strict measurement accuracy, such as quality inspection in precision manufacturing.
Filtering & Signal Processing: The built-in single-pole low-pass filter has a 3dB cutoff frequency at 34Hz (±25%), effectively removing high-frequency noise to enhance signal stability and reliability. This is particularly critical in industrial environments with heavy electrical interference, ensuring input signals remain free from noise pollution during transmission and providing an accurate data foundation for subsequent control decisions.
Fault Detection & Indication: Equipped with a comprehensive fault detection mechanism, it realizes local signal indication via LED indicators. Sixteen red LEDs indicate channel faults, and 16 green LEDs show channel activation; additionally, 1 red LED signals external faults, and 1

Application Fields
Industrial Automation Production Lines
In automated production lines for automotive manufacturing, electronic device production, etc., it is used to collect analog signals from various sensors (such as position sensors, pressure sensors) — providing precise data support for production line automation control. This ensures efficient and stable operation of the production process, enabling accurate monitoring and adjustment of the production flow.
Process Control Industries
In fields like chemical, petroleum, and power industries, precise measurement and control of process parameters (temperature, pressure, flow, etc.) are critical. The 140ACI04000 module can acquire these analog signals in real time, transmit them to the control system for analysis and processing, and assist operators in promptly adjusting production parameters to ensure production safety and product quality stability.
Intelligent Building Control Systems
In large commercial buildings or smart buildings, it monitors and controls the operating status of equipment such as air conditioning systems, lighting systems, and water supply/drainage systems. By collecting analog signals (temperature, humidity, current, etc.), it realizes intelligent management of building equipment, improves energy efficiency, and creates a comfortable and convenient environment for users.
