Description
The ABB TU834 3BSE040364R1 is a 50V extended module termination unit (MTU) designed for the ABB S800 I/O system used in industrial automation applications. Here’s a breakdown of its functionalities, specifications (based on available information), and where to find more details:
Function:
- The TU834 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 connected I/O modules. The exact number of modules supported depends on the specific model variant (standard or extended).
Specifications (based on available information):
- Number of Channels: Information on the exact number of channels supported by the TU834 3BSE040364R1 is limited. However, based on the designation “extended” it likely supports more channels than the standard TU834 variant (potentially 16 or more channels).
- Voltage Rating: 50V 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.
- Additional Features:
- May provide connection points for field signals (sensor signals) up to 50V DC.
- May not include a shunt stick (a component used for current measurement in some applications).
Applications:
The TU834 3BSE040364R1 is specifically used within the ABB S800 I/O system for industrial automation applications. It plays a crucial role in enabling communication and potentially low-voltage power supply between the S800 controller and various I/O modules like:
- Digital input/output modules (up to the supported channel count)
- Analog input/output modules (up to the supported channel count)
- Specialty modules for temperature, pressure, or other signal types (limited by the channel capacity and voltage rating)
