Legend
1 Controller (e.g., LION, EAGLE, HAWK, etc.)
2 Cable (power, L
ONWORKS) connection from controller to
L
ONWORKS Bus I/O Modules
3 Swivel label holder
4 Cable connection between L
ONWORKS Bus I/O Modules
on separate DIN rails
5 Bridge connectors between L
ONWORKS Bus I/O Modules
on same DIN rail
6 Stopper (from 3
rd
-party supplier)
7 Auxiliary terminal packages
LEDs
Each CentraLine LONWORKS Bus I/O Module is equipped
with:
one green power LED
one yellow service LED
Overvoltage Protection
The inputs and outputs of all CentraLine analog and binary
I/O modules are protected against short circuit, 24 VAC
+20%, and 40 VDC.
In the case of the relay outputs of other CentraLine I/O
modules (i.e., relay output modules, floating output modules,
and mixed I/O modules), appropriate fusing must be provided
to ensure that permissible load currents are not exceeded.
See also sub-section "Features" in section "Relay Output
Modules" on pg. 14.
Service LED
Each LONWORKS Bus I/O Module is equipped with a yellow
service LED (status: yellow/OFF) for easy diagnosis of
failures.
LonWorks Service Button
Each LONWORKS Bus I/O Module is equipped with a
L
ONWORKS service button.
Microprocessors
Each LONWORKS I/O Module is equipped with an FTT-10A
transceiver (link power-compatible) and can thus be used with
any L
ONWORKS controller.
In addition to the main microprocessor, the L
ONWORKS Bus
I/O Modules also have their own Neuron chip (3120).
