ABB | TU841|Terminal Unit
Description
The TU841 is a terminal unit designed for ABB's Freelance series controllers, specifically for applications requiring non-redundant I/O modules. It provides a secure and organized connection point for wiring and supports the installation of I/O expansion modules. The TU841 ensures easy access for maintenance and module replacement without disturbing the wiring.
Features
- Supports non-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.
