KNX ENO 634- KNX Gateway for EnOcean (previous versions).

Uni/bidirectional gateway between wireless EnOcean devices and the KNX bus. Over 100 device profiles (EEP EnOcean Equipment Profiles) allow simple and secure connection of EnOcean sensors and actuators to KNX installations.

The KNX ENO 634 unit acts as a bidirectional gateway between EnOcean radio devices and the KNX/EIB bus. With this device, commands and measured values from wireless EnOcean sensors can be transferred to the KNX bus, for example, to control KNX actuators. Wireless EnOcean actuators can also be controlled via KNX. For EnOcean sensors, the device is based on so-called EnOcean Equipment Profiles (EEP). The implemented profiles are mostly specified in the sensor data sheets. For controlling EnOcean actuators, the corresponding EEPs are emulated.

This means that the gateway sends radio telegrams like a push-button or a window contact. In addition, the gateway supports logic and control functions and is equipped with a radio repeater.

### Wide range of functions and 32 channels
The KNX ENO 634 is organized into 32 channels. Each channel can be assigned to one of the following functions:

### Connection from EnOcean sensor to KNX:

- Switching and contact functions
- Switching
- Dimming
- Shutter up/down
- Scene
- Window contacts
- Window handles
- Access card switches
- Push buttons
- Temperature sensors
- Humidity sensors
- Light sensors
- Presence sensors
- Gas sensors
- Room control devices
- Automatic counting devices
- Environmental sensors (weather station)
- 

### Connection from KNX to EnOcean actuator:

- Relay
- Dimmer
- Shutter
- HVAC actuators (valves)

### Control / logic:

Device and channel configuration is done via ETS software through the KNX bus. The keys and display on the device are used for learning wireless components.

- Timer
- Delay
- Tracking circuit
- Control
- Two-point controller (byte and float)
- Continuous controller
- Heat demand requirements
- Lighting control
- Logic functions
- Gates (e.g. AND, OR, XOR)
- Toggle
- Other
- Trigger
- Encoder
- Watchdog

### Mounting and connection

Mounting can be done on a wall surface (e.g., masonry or wood). The mounting holes correspond to a 55 mm flush-mounted box. The device is powered via the bus.

### Repeater function

The repeater function is used to extend the distances between sensors and actuators. The KNX ENO 634 is a so-called level 1 radio repeater.

### Bus monitoring function

The integrated bus monitoring function is used for system diagnostics directly on the device. The device can display both EnOcean and KNX telegrams.

## Technical specifications

- 16/24/32 channels for sensors, actuators or logic.
- Integrated logic and control functions
- Support for over 100 profiles (EEP)
- Integrated graphic display
- Connections: KNX, internal antenna
- Housing for wall mounting, white
- Dimensions (LxWxH): 81 x 81 x 25 mm

### Note:

For new installations, KNX ENO 626 secure and KNX ENO 636 secure are recommended.
