Product Introduction
ABB GRBTU-01 (reference number 3BSE013175R1) is the terminal unit of the industrial automation control system or the Module Termination Unit (MTU). The terminal unit is a common element in industrial automation systems, including DCS (Distributed Control System), PLC (Programmable Logic Controller), and fieldbus systems. It acts as the link between the module and the rack backplane, and provides power input, signal transmission, and system interfaces to the control module.

Technical features
1 . Communication and Protocol Support
Support common industrial protocols (such as Modbus TCP/RTU, PROFINET, PROFIBUS DP, IEC 61850, etc., depending on the firmware/application configuration).
Multiple physical interfaces are available, such as Ethernet RJ45, RS-485, and Profibus interfaces.
2. Modular installation design
Compact size and lightweight design, suitable for installation on DIN rails or in control cabinets.
Some application versions can be directly integrated into the ABB CPS/DCS/PLC architecture through the rack.
3. Industrial-grade applicability
24V DC power supply design, suitable for the power supply system of industrial control cabinets.
It has an IP20 protection level and is suitable for general industrial indoor environments.
4. Scalability and Compatibility
It can be connected with various on-site devices to establish a data link between the local I/O and the central control system.
Functional Advantages
✔ Protocol Conversion and Integration Capability
GR BTU-01 3BSE013175R1 module enables the interoperability between the protocols used by on-site equipment (such as Modbus/Profibus/IEC 61850, etc.) and the protocols required by the control system, thereby reducing the compatibility challenges between on-site equipment and the main network.
✔ Supports multiple network topologies
The GR BTU-01 3BSE013175R1 module integrates multiple communication interfaces and physical ports, and can be connected to Ethernet, serial buses and fieldbus networks, providing a flexible on-site configuration method.
✔ System Edge Data Aggregation
GR BTU-01 3BSE013175R1 can serve as a remote data collection point or an edge protocol agent, aggregating and organizing the data from multiple on-site devices and transmitting it to the main control system. This helps to reduce the load and complexity of the main network.
✔ Flexible installation and deployment
The compact design and standard power/communication interfaces make it easy to deploy within the control cabinet, and also facilitate integration into existing control systems.
Use ABB GRBTU-01 together with ABB LDGRB-0.1.
In ABB automation systems (such as AC 800M / S800 I/O architecture), when it is necessary to assemble a complete I/O rack or a distributed control node, GRBTU-01 and LDGRB-01 are often two key units that are used together. They respectively perform different electrical/bus termination and system integrity protection functions.
GRBTU-01 (Module Termination Unit)
As the terminal unit of the module, it is mainly used for signal termination, electrical interface,ce and power bridging within the control system rack.
It is usually located in the main control rack or main backplane system, providing unified connection terminals and signal bridging functions for I/O modules, communication modules, etc.
This unit ensures that the signals, power supply, and logical connections between the module and the control system are stable and reliable.
LDGRB-01 (Local Distribution Rack Bus Terminator / I/O Module)
LDGRB-01 is a unit specifically designed for the S800 I/O bus termination of Local Distribution Units or for analog/digital I/O functions.
Its main function is to perform termination matching for the I/O rack bus.
