12.4  esserbus
®
 transponder 12 relays (Part No. 808610.10)  
The esserbus
®
 transponder works as a loop device on the loop, it is possible to expand the number of outputs 
per ESSER FACP.  
In ‘potential-free’ mode, no external switching voltage is required for relays K1 to K11.  
In ‘monitored’ mode, the relays can be switched with an external power supply (UBext.). The monitoring of 
UBext. enables a fault warning on the FACP if the permissible tolerance limits are not met. ‘Monitored’ mode is 
configured using the service and programming software tools 8000. 
The contact behaviour (NC / NO functionality) of relay contacts K1 to K11 can be individually programmed in the 
customer data. The functionality as a common fault relay is permanently assigned to relay 12 (NO contact).  
The maximum line length from the transponder to the external tool is up to 1000 m. There is also the option of 
operating the transponder with the loop isolator (Part No. 788612). 
 
•  Only one loop address is needed per transponder 
•  Max. 100 transponders per FACP 
•  Max. 32 transponders per loop 
•  Max. 32 transponders per detector zone
