7 Auxiliary terminal packages
LEDs
Each CentraLine L
ON
W
ORKS
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 L
ON
W
ORKS
Bus I/O Module is equipped with a yellow
service LED (status: yellow/OFF) for easy diagnosis of
failures.
LonWorks Service Button
Each L
ON
W
ORKS
Bus I/O Module is equipped with a
L
ON
W
ORKS
service button.
Microprocessors
Each L
ON
W
ORKS
I/O Module is equipped with an FTT-10A
transceiver (link power-compatible) and can thus be used with
any L
ON
W
ORKS
controller.
In addition to the main microprocessor, the L
ON
W
ORKS
Bus
I/O Modules also have their own Neuron chip (3120).
