24 Technical Data
24.1 esserbus
®
Analog loop module (Part no. 784382)
Recommended connecting
cable
: Line transmission cable IY-St-Y; 0.8 mm cable cross
section
Max. analog loop resistance 75
Ω
with 0.8 mm cable cross
section(measured from A+ to B+) 130
Ω
with 0.6 mm cable
cross section
These values correspond to a total length of a analog loop
of approx. 2000m
Power consumption : 25 mA
Short-circuit current limit : 60 mA
CPU-failure function : Processor with capability of operating in CPU failure mode
Internal voltage supply : +12V and +26 V via connector strip
24.2 esserbus
®
-PLus Analog loop module (Part no. 804382)
In esserbus
®
-PLus Systems with addressable audible loop devices the number of analog loops is
limited to 4. No more than 4 analog loop modules (Part-no. 804382) should be installed per panel.
