Overview

ABB 1MRK001967-AA is a modular temperature measurement module specially designed for the field of industrial automation, belonging to the ABB 500 series industrial control product system. It is mainly responsible for the accurate collection, processing and transmission of temperature parameters in industrial production processes, and is a key component for perceiving temperature information in industrial control systems.

Technical Parameters

• 
  

• Power Parameters: The working power supply is 24V DC, with an allowable voltage fluctuation range of ±10% and a rated power consumption of ≤6W, which can adapt to the fluctuation of the industrial on-site power supply and ensure stable power supply for the module.

• Measurement Channels: Equipped with 8 independent temperature measurement channels, which can collect multiple temperature signals at the same time to meet the needs of simultaneous monitoring of multiple measuring points.

• Sensor Type Adaptation: Supports various mainstream temperature sensors such as thermocouples (types J, K, T, E, R, S, B) and thermal resistors (Pt100, Pt1000, Cu50, Cu100), with a wide adaptation range.

• 
  

• Measurement Range: The measurement range of thermocouples is -200℃-+1800℃ (varies by model), and the measurement range of thermal resistors is -200℃-+850℃, which can cover the temperature measurement needs of most industrial scenarios.

• Measurement Accuracy: The measurement accuracy of thermocouples is ±0.1℃ (in the range of -50℃-+150℃) or ±0.1% of the measured value (when exceeding the above range); the measurement accuracy of thermal resistors is ±0.05℃ (in the range of 0℃-+100℃) or ±0.05% of the measured value (when exceeding the above range), ensuring the accuracy of temperature data.

• 
  

• Sampling Rate: The maximum sampling rate per channel is 10Hz, which can quickly capture the dynamic changes of temperature, meeting the requirements of real-time monitoring in industrial processes.

• Communication Interface: Communicates with the controller through the system bus, supports Modbus RTU protocol, and the communication rate can reach 1Mbps, ensuring efficient transmission of temperature data.

• Environmental Parameters: The operating temperature range is -10℃-+60℃, and the storage temperature range is -40℃-+85℃; the relative humidity is 5%-95% (non-condensing); the protection level is IP20, suitable for installation in control cabinets.

• Physical Specifications: Adopting a modular design, the size is approximately 140mm×100mm×70mm (length × width × height), and the weight is about 350g. It supports DIN rail mounting, saving installation space.

Functional Features

• 
  

• Multi-channel Accurate Measurement: The 8 independent channel design can collect temperature from multiple measuring points at the same time, and each channel has high-precision measurement performance, which can accurately reflect the temperature status of each measuring point, providing a data basis for the precise regulation of industrial production processes.

• Wide Sensor Adaptation: Compatible with various types of temperature sensors such as thermocouples and thermal resistors, it can be connected with different sensors without additional signal conversion equipment, reducing the difficulty and cost of system integration and improving the versatility of the module.

• 
  

• Fast Dynamic Response: The high sampling rate of 10Hz can quickly capture the instantaneous changes of temperature. For industrial scenarios with rapid temperature fluctuations (such as chemical reaction processes), it can feedback temperature information in time, facilitating the control system to make adjustments quickly.

• Outstanding Anti-interference Ability: Adopting advanced filtering technology and electrical isolation design, it can effectively resist electromagnetic interference, radio frequency interference, etc. in industrial sites, reduce the impact of external factors on temperature measurement, and ensure the stability and reliability of measurement data.

• 
  

• Intelligent Diagnosis Function: Equipped with sensor disconnection and short-circuit detection functions. When the sensor fails, it can send an alarm signal in time and upload it to the control system through the communication interface, facilitating maintenance personnel to quickly locate problems and reduce troubleshooting time.

• Flexible System Integration: As a standard module of the ABB 500 series, it can be seamlessly integrated with bus adapters, controllers, etc. of the series, and is also compatible with third-party control systems, facilitating the construction of a complete industrial automation monitoring and control system.
