ABB Universal E/A-Konzentrator, 32fach – Overview
The ABB Universal E/A-Konzentrator, 32fach (model UK/S 32.2) is a versatile, high‑performance input/output concentrator designed for KNX and I‑Bus networks. It consolidates up to thirty‑two discrete signal lines into a single compact module that can be mounted on a DIN rail or installed in an IP20 enclosure. The device supports both DC current types and is engineered for reliable operation in demanding building automation environments.
Key Functionalities
- 32 discrete input/output channels – Each channel can be configured as an input or output, providing flexible control over a wide range of sensors and actuators.
- DC current support (0.1 A nominal) – The concentrator is rated for a nominal DC current of 0.1 A, making it suitable for low‑power KNX devices such as dimmers, switches, and sensors.
- Integrated bus coupling – The module can be directly coupled to the KNX or I‑Bus network, eliminating the need for additional wiring harnesses.
- Power output of 1.9 VA – Each channel delivers a maximum power of approximately 1.9 VA, sufficient for most standard building automation components.
- DIN rail mounting – The device features a DIN‑rail mount, allowing straightforward installation in control cabinets or distribution boards.
- No Ethernet interface – Focused on traditional bus communication, the concentrator does not include an Ethernet port, ensuring a streamlined and cost‑effective design.
