The EK-WL8-EXP Expander Module increases radio coverage of an Ekho Translator Module, allowing the use of the system in larger buildings and in
difficult wireless environments. Multiple Expanders can be utilised in a micro cell structure to provide a solution to large, complex systems.
When multiple Expander Modules (two or more) are used, these provide a MESH solution maintaining the wireless systems integrity. The system allows
up to 126 Expander Modules or field devices to be configured to any one Translator Module.
Any combination of Ekho wireless devices can be connected to the Expander Module. The Expander Module transmits the intelligent device information
from the field devices to the Loop Translator Module using a highly stable bi-directional radio communication protocol. The system parameters are
programmed into the Expander Module via the Translator Module.
The Expander Module Is fitted with two Internal antennas reducing signal fading and ensuring reliable radio communications. Optional back box available.
