ABB NTST01 Time Sync Link TU Time Sync Link Terminal Unit

ABB NTST01 Time Sync Link TU Time Sync Link Terminal Unit

Product positioning and core identification

NTST01 is a Time Sync Link Terminal Unit (TU) launched by ABB, which belongs to the terminal module product category in industrial control systems. Its core function is to provide terminal connection and signal processing for specific control system components of the time synchronization link. It needs to be used in conjunction with ABB supporting equipment such as TKM, SET, NKTK, NKST, and is widely applicable to industrial control systems such as ABB Symphony Harmony INFI 90. It is typically used in process control scenarios such as power, chemical, and energy that require time synchronization accuracy.

Core Product Information

1. Basic identification and classification

Category specific parameters

Product model NTST01 (ABB official model identification, unique corresponding to time synchronization link terminal unit function)

Product type: Modulus Termination Unit Module (used for signal terminal connection and transfer)

The full English name of the product description is "Time Synch Link TU", which is translated as "Time Synchronization Link Terminal Unit" in Chinese. It specifies the terminal function positioning related to time synchronization

The applicable system belongs to the ABB control system product system, specifically classified as "Control System Products>Control&Communication>S+HR>S+HR - Termination Units", and is also compatible with the I/O module of the "Symphony Harmony INFI 90" system (such as IMASI23 analog slave input module), supporting prefabricated cable connections

2. Physical specifications and weight

Size parameters:

Depth (Length): 96.52 mm;

Height: 238.76 mm;

Width: 220.98 mm;

The overall design is compact, suitable for standard installation space inside industrial control cabinets, and can be co arranged with other INFI 90 series modules.

Weight: The net weight of the product is marked as 0 kg (in reality, it should be a lightweight design, and the exact weight should be based on the actual product or more detailed specifications, estimated to be several hundred grams, to reduce the load-bearing pressure of the control cabinet).

Compliance and Environmental Information

1. Customs and tariff codes

HS code: 85371091, corresponding to the product category of "electrical control or distribution boards, panels, consoles, etc. with voltage not exceeding 1000V, equipped with at least two types of 85.35 or 85.36 equipment, including instruments or numerical control devices (excluding 85.17 exchange equipment)", clarifying the attributes of its industrial electrical control accessories for import and export customs clearance and tariff accounting.

Customs tariff number: associated with HS code, following the tariff policies of the corresponding country/region for industrial electrical products.

2. Environmental classification

WEEE category: Class 5 "Small Equipment", defined as "equipment without external dimensions exceeding 50cm", meets the classification requirements of the EU Waste Electrical and Electronic Equipment Directive (WEEE), and facilitates compliant recycling and disposal of equipment after disposal.

Number of batteries: 0, which means the product does not include built-in batteries, so there is no need to worry about battery aging, replacement or environmental protection issues, reducing maintenance costs and environmental impact.

Adaptation and application scenarios

1. Requirements for supporting equipment

The product needs to be used in conjunction with specific models of ABB equipment, and the document clearly indicates "Use with TKM, SET, NKTK, NKST". It is speculated that these devices are the sending end, relay end, or other related control modules of the time synchronization signal. NTST01 serves as the terminal unit responsible for completing the physical connection and signal adaptation of the time synchronization link between these devices and the system I/O module (such as IMASI23).

2. Typical application scenarios

Target System: Mainly compatible with ABB Symphony Harmony INFI 90 distributed control system, which is widely used in large-scale process industries such as thermal power plants and petrochemical plants;

Core function: To undertake the terminal transfer task of time synchronization signals in the system, ensuring that analog input modules such as IMASI23 can receive accurate time synchronization signals, thereby ensuring the accuracy of timestamp for process data acquisition (such as SOE event sequence recording), and providing reliable time benchmarks for fault tracing and process analysis;

Installation scenario: It needs to be installed in an industrial control cabinet, connected to other modules through prefabricated cables, and adapted to harsh environments such as dust and vibration in industrial sites (specific environmental adaptability parameters such as temperature and protection level need to refer to supplementary documents, which are not explicitly mentioned in this manual).
