Description
The ABB TU811V1 is an 8-channel, 250V compact module termination unit (MTU) designed for the ABB S800 I/O system used in industrial automation applications. Here’s a breakdown of its functionalities and where to find more information about it:
Function:
- The TU811V1 acts as an intermediary between the S800 I/O modules and the ModuleBus, a communication bus within the S800 system.
- It terminates the ModuleBus signal, preventing signal degradation along the bus as more modules are connected.
- It distributes the ModuleBus signal to up to 8 connected I/O modules.
Specifications (based on available information):
- Number of Channels: 8 channels
- Voltage Rating: 250V DC
- Compatibility: Designed for the ABB S800 I/O system and ModuleBus communication protocol.
- Dimensions: Specific dimensions are difficult to find without a datasheet, but being a compact unit, it’s likely suitable for space-constrained industrial control cabinets.
- Maximum Current per I/O Channel: 3 Amperes (according to some retailers)
Applications:
The TU811V1 is specifically used within the ABB S800 I/O system for industrial automation applications. It doesn’t directly interact with sensors or actuators but plays a crucial role in enabling communication between the S800 controller and various I/O modules like:
- Digital input/output modules
- Analog input/output modules
- Specialty modules for temperature, pressure, or other signal types
