1. Overview
The ABB TU849 module terminal unit is used in the field of industrial automation. It comes from the well-known brand ABB, with excellent performance and rich functions, providing strong support for industrial control systems.
2. Usage Parameters
Power input: TU849 supports 24V DC power input, voltage range 19.2~30V, and stable voltage.
Power consumption: TU849 has a total power consumption of 2.5W, with good energy saving effect.
Mechanical button configuration: 4 mechanical buttons, 6 positions for each button, providing 36 different configuration combinations to meet the requirements of different module types, and a flat screwdriver can change the configuration.
Wiring specifications: The acceptable wire specifications of TU849 are single wire 0.2~2.5 square millimeters, stranded wire 0.2~2.5 square millimeters (corresponding to 24-12AWG), and the recommended torque is 0.5Nm.
Supported communication protocol: TU849 is not a master-slave device of the module bus, but a single module bus connection.
3. Product Features
Dual power connection: TU849 has a dual power connection function to ensure stable operation of the equipment. Even if one power supply is powered off, the other power supply can support the resident operation mode of the equipment and continue to power the system.
Cluster address setting: TU849 can set the cluster address through the rotary switch, ranging from 1 to 7, which is convenient for distinguishing and managing different devices in complex industrial control systems.
Anti-misinsertion design: The mechanical locking design can effectively prevent the insertion of the wrong type of module, prevent equipment failure and system errors caused by module mismatch, and ensure the reliability and stability of system operation.
Rail installation and locking: It can be installed on a standard DIN rail, and the mechanical locking system can be used to firmly fix it on the rail to ensure the stability of TU849 in harsh environments such as vibration. At the same time, the lock can be locked and unlocked with a screwdriver, which is very convenient for installation and removal.
4. Scope of Application
ABB TU849 is widely used in various industrial automation scenarios, such as oil and gas, chemical, electric power, water treatment and other industries. In DCS, it plays the role of a key connection and communication component to realize data transmission and signal conversion between different modules. It can well control and monitor the scattered equipment on large industrial production lines to ensure the smooth progress of the production process. Due to its reliable performance and flexible configuration, it is also very suitable for key control links with strict requirements on system stability and reliability.
