Description

ABB TU831V1 extended terminal block element

Electrical parameters
Rated voltage: 250V.
Rated current: The maximum rated current for each channel is 3A.
Number of channels: There can be up to 8 I/O channels at most.

Functional parameters
ModuleBus function: Assign ModuleBus to the I/O module and the next MTU, and generate the correct address for the I/O module by transferring the output position signal to the next MTU.
Channel isolation: It features 8 isolated on-site signal channels, which can effectively prevent signal interference.

Environmental parameters
Operating temperature: Generally 0℃ to + 55℃, certified for + 5℃ to + 55℃.
Storage temperature: -40℃ to + 70℃.
Relative humidity: 5% to 95%, no condensation.

Application scenarios
Power system: In power systems such as power plants and substations, it can be used to connect power monitoring equipment (such as voltmeters and ammeters), protection devices (such as relays), and control systems to achieve real-time monitoring and protection of the operating status of the power system. When an abnormality occurs in the power system, it can quickly cut off the faulty circuit to protect the safety of equipment and personnel. For instance, in a substation, a voltmeter for monitoring the busbar voltage and a relay for protecting the busbar are connected. When an abnormal voltage occurs, the relay can quickly act through the TU831V1 to cut off the relevant circuit.
Process control system: In the field of process control such as petroleum, chemical engineering, and water treatment, various process parameter detection instruments (such as flow meters, level gauges, and pressure transmitters) can be connected to the control system to achieve precise control of the production process. By accurately reading and processing the signals of these instruments, it is ensured that the production process proceeds within the set parameter range, thereby enhancing product quality and production efficiency. For instance, in petrochemical production, flowmeters and controllers are connected to precisely control the material conveying volume based on flow signals, ensuring the stability of the production process.
