Description
The ABB TU838 3BSE008572R1 is an 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, and where to find more details:
Function:
The TU838 acts as an intermediary between the S800 I/O modules and the ModuleBus, a communication bus within the S800 system:
- Terminates the ModuleBus signal, preventing signal degradation as more modules are connected.
- Distributes the ModuleBus signal to up to 16 I/O modules (possible due to the “extended” designation).
Specifications:
- Number of Channels: 16 (potentially)
- Voltage Rating: 50V DC
- Compatibility: Designed for the ABB S800 I/O system and ModuleBus communication protocol.
- Dimensions: Information on specific dimensions is limited without a datasheet, but being a compact unit, it’s suitable for space-constrained industrial control cabinets.
- Additional Features:
- May include 2 fused transducer power outlets for powering specific sensor types.
- May have 16 signal terminals for connecting various input/output signals.
- May have separate L+ and L- terminals for power connections.
Applications:
The TU838 3BSE008572R1 is used within the ABB S800 I/O system for industrial automation applications:
- Enables communication between the S800 controller and up to 16 I/O modules.
- Provides fused power for specific sensors or transducers (if applicable).
- Provides connections for various input/output signals.
