ELECTRONIC LOGGER – INSTRUCTIONS MANUAL V2.2x B
INTRODUCTION
FieldLogger is an equipment that reads and registers analog
variables. It works as an electronic data logger, storing logged
information in its internal memory for later analysis. It can also work
as a real-time remote measuring module, which does not have
internal memory and only logs information and transmits them to a
supervisory system.
Its 8 configurable input channels, digital input and alarm outputs,
backup power, etc, make it very versatile, which makes possible to
use it in a large number of applications.
It is configured through an easy-to-use software. The equipment is
provided with the software, which runs on Windows98 platform and
higher.

INPUTS
The logger has 8 input channels. You can configure the type of signal
to be read by each channel. All types of input channels accepted are
factory calibrated and no further adjustment is required. The user
defines and configures the channels that will be in use, and disables
the others.
The types of input channels accepted by the logger and their
maximum ranges are listed in Table 01.
MEASUREMENT INTERVAL
The speed of input channels readings depends on the number of
channels enabled and type of input programmed for each channel.
Each channel requires a reading time of about 50 ms. Programmed
channels with Pt100 input need more than 50 ms for cable length
compensation calculations. 150 ms are required for internal
processing, regardless of the number of channels enabled. Thus, if
only one channel is enabled, readings will take place at every 200 ms
(50 + 150). If this channel is programmed to Pt100, 250 ms are
required between readings (50 + 50 + 150).
Required time to read the eight channels is 550 ms. If they are
configured as Pt100 input, required time will be 950 ms.

OUTPUTS
The logger has two relay outputs (ALM1 and ALM2) that can work as
Alarm or Digital Output.
When configured as Alarm, they act as configured by the user.
As Digital Outputs they are remotely controlled through serial
communication.
