ABB IMDSI02 analog input module

• Channel Configuration: 8 single-ended analog input channels, supporting inter-channel isolation, each channel can be independently configured with signal type.​

• Input Signal Types: Compatible with 4-20mA current signals, 0-10V voltage signals, and supports thermocouple (K, J, T types) and thermal resistance (Pt100, Cu50) signal inputs.​

• Measurement Accuracy: Current/voltage signal measurement accuracy ±0.1% FS (full scale), thermocouple measurement accuracy ±1℃, thermal resistance measurement accuracy ±0.1℃ (-50℃~200℃).​

• Sampling Rate: Maximum sampling rate per channel is 100Hz, supporting synchronous sampling or sequential sampling mode to meet dynamic signal acquisition requirements.​

• Isolation Performance: Inter-channel isolation voltage ≥2.5kVrms, isolation voltage between analog input and digital output ≥5kVrms, common-mode interference rejection voltage ≥2kV.​

• Operating Environment: Operating temperature -25℃~70℃, storage temperature -40℃~85℃, relative humidity 5%-95% (non-condensing), protection class IP20.​

• Power Requirement: 24V DC±10% power supply, power consumption ≤8W (full load).​

• Communication Interface: Communicates with PLC main module via backplane bus, supports PROFIBUS DP protocol, data update cycle ≤10ms.​

• Dimensions: Width×height×depth approximately 45mm×175mm×120mm, DIN rail mounted, supports hot swapping.​

• Certification Standards: UL, CE certified, compliant with IEC 61131-2 and EN 61000-6-2 industrial standards.​

• High-Precision Multi-Type Acquisition: Supports current, voltage, thermocouple, thermal resistance and other signal types, with measurement accuracy up to ±0.1% FS, which can accurately capture small signal changes, adapting to multi-parameter monitoring scenarios such as temperature, pressure and liquid level.​

• Strong Isolation and Anti-Interference: High-voltage isolation design between channels and system effectively suppresses electromagnetic interference and common-mode interference in industrial fields, ensuring stable signal acquisition in strong interference environments such as frequency converters and motors.​

• Flexible Configuration Capability: Each channel can independently set signal type, range and filtering parameters, and realize sensor adaptation through software programming without hardware jumpers, simplifying on-site debugging process.​

• Fast Dynamic Response: 100Hz high sampling rate combined with low-latency data transmission can track rapidly changing process signals (such as instantaneous pressure fluctuations) in real time, meeting dynamic control requirements.​

• Industrial-Grade Reliability: Wide temperature operating range and anti-vibration design (5g acceleration, 10-500Hz), adapting to harsh industrial environments such as metallurgy and chemical industry, with mean time between failures (MTBF) ≥10⁶ hours.​

• Process Industry Monitoring: In chemical reactors, oil pipelines and other scenarios, collect analog signals such as temperature, pressure and liquid level, monitor reaction status in real time, and provide data basis for process parameter adjustment.​

• Manufacturing Production Lines: Monitor parameters such as injection molding machine barrel temperature, hydraulic system pressure, and conveyor speed to ensure stable production process and improve product quality consistency.​

• Energy and Utilities: In power plant boilers and water plant pump stations, collect steam flow, water pump pressure and other signals to realize energy consumption metering and equipment operation status monitoring.​

• Environmental Monitoring Systems: Adapt to air quality sensors, water quality detectors and other equipment, collect environmental parameters such as dust concentration and pH value, and support real-time upload of environmental protection data and over-limit alarm.​

• Metallurgy and Building Materials: In steel blast furnaces and cement kilns, collect temperature distribution in the furnace through thermocouples, monitor high-temperature smelting process, and ensure production safety.​

• Sensor wiring must use shielded cables, with the shield layer grounded at one end (control cabinet side). Avoid parallel laying of signal cables with high-voltage cables to reduce electromagnetic interference.​

• Wiring for thermal resistance and thermocouple signals should be away from power cables. Thermocouple compensation wires must match the thermocouple type to avoid cold junction compensation errors.​

• Module installation must ensure the guide rail is firmly fixed to prevent loose wiring due to vibration; hot swapping should be performed when the system is powered off or the module is in standby state to prevent data loss.​

• Before first use, each channel's zero point and range must be calibrated through configuration software, especially for high-precision measurement scenarios (such as laboratory equipment), and calibration is recommended once a year.​

• The power supply must use a regulated power supply to avoid voltage fluctuations affecting measurement accuracy; avoid installing high-power switching power supplies, contactors and other interference sources near the module.​
