Factoryline Bluetooth EPA – the robust Ethernet wireless bridge

Factoryline Bluetooth EPA

The FL BT EPA Bluetooth Ethernet port adapter connects Ethernet-capable automation modules with the controller network wirelessly. The compact and robust Ethernet port adapter comes with integrated wireless module and antenna. The IP65 turnkey solution is installed directly in the field and connected to the automation device via an Ethernet cable with M12 connection technology. The benefit for you: extremely straightforward integration into your application.

Bluetooth: the reliable wireless technology for industrial use

The EPA modules were developed for reliable and fault-free communication of control signals, e.g. via PROFINET. The advantage of using Bluetooth technology is that it provides extremely robust wireless communication, which is particularly reliable even under harsh industrial conditions.

Easy and safe setup, thanks to automatic configuration

Mode button  

Easy configuration, thanks to the Mode button

Secure point-to-point and small networks can be set up quickly and easily without configuration with the Mode button. Alternatively, configuration can also be conveniently carried out via web browser.

Fault-free parallel operation with WLAN

Coexistence of WLAN and Bluetooth  

Perfect coexistence with WLAN networks thanks to low emission mode and black channel listing

The Bluetooth EPA modules enable fault-free parallel operation with other WLAN systems, thanks to efficient use of frequency gaps. In addition to the automatic coexistence mechanism of Bluetooth, the EPA modules also offer the following:

  • Low emission mode, for low interference emissions when establishing connections
  • Black channel listing: allows configuration of up to three WLAN channels whose frequency ranges will not be used by the EPA module
