Description
The 1208L is an Analog Input Module for LonWorks network in building
automation. Its peripheral scope has been specially designed for the use as
temperature or humidity sensor device spreading control of applications such
as valve control or lighting control thru Lux sensor.
For the use in building automation control the 1208L Analog Input Module
realizes 8 independent input channels.
The LonMark object available per channel flexible use of the 1208L;
Furthermore there are several Network Variable Type Translator functions for
the operation by network variable type translator function. The configuration of
the building automation application is effected via any LonWorks network
management tool.
Of course, the 1208L Analog Input Module is also freeing programmable in
Neuron C. As a flash module is used the application can be load via the
LonWorks network, making the 1208L an I/O controller, e.g. for detail info

4.1 Hardware
Survey
The 1208L Analog Input Module disposes of eight output circuit for each.
The output circuit can be accept individually input 0~10VDC or 4~20mA
single.
4.2 Operation and Display Elements
The 1208L Analog Input Module is fitted with a service button accessible
via a small gap on the front panel (see Figure. 1.1,
8
). Activation of the
buttons generates a service-pin message transmitted via the LonWorks
network. The processor status as well as the service-pin status are
displayed by the service LED (figure. 1.1,
A
), which is on while the service
button is activated. By use the network management function Wink the
service LED flashes.
Furthermore the 1208L Analog Input Module is fitted with a reset LED
(figure. 1.1,
B
), displaying the availability of device occur reset. The LED is
connection to an I/O pin of the Neuron chip processor.
