ABB NTRL03 Remote Link Termination Unit

ABB NTRL03 Remote Link Termination Unit

Basic information

Series: Part of ABB Bailey's Infi 90 and Net 90 series, which work in conjunction with other components in the series to provide reliable communication links for industrial automation systems.

Place of origin: Originally from Sweden.

Functionality

Signal transmission and communication functions:

Remote Link Connection: It is mainly used to establish and maintain communication links between remote devices. It can receive signals from other terminal units or devices and accurately transmit them to the target device or system, ensuring effective data exchange between devices in different locations and realising remote monitoring and control of industrial processes.

A variety of communication interface support: with a variety of communication interfaces, it can adapt to different communication protocols and signal types. For example, it supports the communication link connection with other TRL terminal units and station serial communication link, which can meet the communication requirements between different devices and facilitate the integration with various industrial equipment.

Signal Processing and Conversion Function: Performs the necessary processing and conversion of the input signal to make it meet the requirements of the target device or system. For example, amplification, filtering and other operations on the signal to improve the quality and stability of the signal to ensure the accuracy and reliability of the signal in the transmission process.

Power Distribution Function: It can provide 24 VDC power supply for the connected devices, providing power support for the normal operation of remote devices, reducing the dependence on external power supply and simplifying the wiring and power configuration of the system.

Technical Parameters

Power Requirements: Input voltage +24 VDC, maximum current 118 mA, powered by 24 VDC bus.

Input and output signals:

Inputs: Including communication link signals from other TRL Terminal Units, station serial communication link signals, etc.

Output: Includes communication link signals to another Terminal Unit, station serial communication link signals, and 24 VDC power supply for the connected station.

Environmental Specifications :

Operating temperature: 0°C to 70°C.

Relative humidity: 0% to 95% at 55°C (non-condensing), 0% to 45% at 70°C (non-condensing).

Electromagnetic compatibility: For normal operation of the equipment, the cabinet door should be kept closed and communication equipment should be located at least 2m away from the cabinet to prevent electromagnetic/radiofrequency interference.
