1746-NT8 SLC 500 thermocouple/millivolt analog input module

Input channel:
It has 8 independent input channels and can simultaneously receive multiple thermocouple or millivolt signal inputs, improving the monitoring and control efficiency of the system.
Compatible Sensor Types: Compatible with various common thermocouple sensor types such as J, K, T, E, S, R, B, and N, and also supports millivolt inputs of+/-50mV and+/-100mV, suitable for different temperature measurement scenarios.
Signal conversion and processing:
By using the delta sigma signal conversion method, the input analog signal can be converted into a digital signal for retrieval and processing by the SLC 500 processor.
Having a digital low-pass filter and a programmable filter frequency that can be selected according to actual needs helps improve the accuracy and stability of the signal.
Suppression of interference capability:
The normal mode suppression frequency is higher than 100dB at 50-60Hz, and the common mode suppression frequency between input and ground is also higher than 100dB at 50-60Hz. It has strong anti-interference ability and can work stably in complex electromagnetic environments.
Protection function:
Provide+/-30V DC and 600W pulse 1ms input overvoltage protection, which can effectively prevent module damage caused by abnormal input signals.
12.5V DC circuit isolation is provided between the input and chassis grounding, as well as between the input and backplane (with a test voltage of 500V DC for 1 minute), ensuring the safety and reliability of the system.
Calibration function: The module automatically calibrates approximately every 2 minutes after being powered on, which helps maintain measurement accuracy.
Status indicator: There are 9 green LED lights used to indicate the channel status and module status, making it convenient for users to quickly understand the working status of the module.
Terminal block: Use a 1746-RT34 (RTB) detachable terminal block to connect input devices. The terminal block includes two Cold Junction Compensation (CJC) sensors with an accuracy of+/-1.72 degrees Celsius.
Application scenarios: Widely used in industrial automation control systems, process control fields, and other applications that require temperature measurement and monitoring, such as chemical, pharmaceutical, power, and other industries.
In summary, the 1746-NT8 module features high-precision measurement, compatibility with multiple input types, strong anti-interference ability, and comprehensive protection functions, making it an excellent thermocouple/millivolt analog input module.

As a pioneer in technology, ABB has received an order from Transpower New Zealand to upgrade its high-voltage direct current (HVDC) transmission lines, which interconnect the transmission networks of the North and South Islands.

It is reported that this high-voltage direct current transmission line connecting the North Island and South Island of New Zealand is an important component of the country’s power grid system and also the power balance system between South Africa. ABB’s Ability MACH control system, as the brain or nerve center of the link, will become a key component of the upgrade.

It is reported that the population of the North Island of New Zealand is more than three times that of the South Island, and in addition to its picturesque scenery, it also provides a large amount of hydroelectric power. Therefore, the demand for electricity in the North Island has greatly increased and relies on the power supply in the South Island. The north-south high-voltage direct current transmission interconnection line, which is over 600 kilometers long, can efficiently transmit clean electricity to high demand areas. The line also plays an important role in the New Zealand electricity market by allowing electricity trading between two islands.

ABB has a historic involvement in this project. The first New Zealand HVDC transmission system was built by ABB (formerly ASEA) in 1965, which was also one of the world’s first HVDC transmission systems at that time. It was originally a bipolar 600 megawatt (MW) link with a mercury arc valve, until 1992 when the original equipment was connected in parallel to a single pole and ABB collaborated with it to debug a new thyristor pole, increasing the capacity to 1040 MW.

It is reported that this upgrade includes the upgrade of Valve 2, which is composed of electrodes, optical fibers, and valve control units based on the latest ABB Ability MACH control system. The upgrade will be completed in 2020, and its implementation will minimize the impact on the power grid and electricity trading market.

This upgrade will improve the reliability and availability of the power grid, thereby enhancing power safety and bringing clean energy to consumers, “said Claudio Facchin, President of ABB’s Power Grid Division.” This project reaffirms our strategic focus on services and commitment to integrating renewable energy, as well as the role of digital technology based on ABB’s capabilities, and consolidates our leading position in HVDC technology, becoming the preferred partner for achieving a stronger, smarter, and more environmentally friendly power grid

ABB pioneered high-voltage direct current transmission technology 60 years ago and has obtained approximately 120 high-voltage direct current transmission projects with a total installed capacity of over 130000 megawatts, accounting for about half of the global installation base.
