ABB | TU833|Terminal Unit
Description
The TU833 is a terminal unit designed for ABB's Freelance series controllers, specifically for applications requiring redundant I/O modules. It provides a secure and organized connection point for wiring and supports the installation of redundant I/O expansion modules. The TU833 ensures easy access for maintenance and module replacement without disturbing the wiring, making it suitable for high-availability systems.
Features
- Supports redundant I/O modules.
- Secure mechanical locking for installed I/O modules.
- Facilitates hot-swapping of I/O modules.
- Suitable for DIN rail mounting or wall mounting via screws.
- Includes dual power supply connectors for redundancy.
Technical Specifications
- Terminals: 40 in total, distributed into 5 groups of 8 channels each (1.0...1.7, 2.0...2.7, 3.0...3.7, 4.0...4.7, 5.0...5.7).
