TE-4024
Issue 2 (27th October 2023) E&OE
• Ethernet connectivity (communicates across a LAN)

• Power over Ethernet (PoE) with battery back-up
• Waterproof case
• Tinytag Connect compatible
The TE-4024 is a temperature data logger that plugs directly into a network
point and communicates across a LAN.
The logger can be managed as a standalone logger, in conjunction with the
standard version of Tinytag Explorer, or as part of a network of loggers, using
Tinytag Connect software.
The data logger measures temperature using four thermistor probes.
The logger records data at user-defined logging intervals and can be
programmed to give alarm alerts, both audible and visual, in the event of a
problem. The logger also has an alarm output that changes state when alarms
are active.
Standalone
When used as a standalone device, the logger connects to a standard version
of Tinytag Explorer across a LAN and is downloaded and configured directly.
Tinytag Connect
When used as part of a Tinytag Connect system, the logger transmits data to
a Windows service that runs the system, called the Connect Gateway. This
data is then viewed, and loggers configured, using the Connect version of
Tinytag Explorer.
Multiple users can access the Connect system simultaneously.
If a logger cannot communicate with the system for any reason, data will be
recorded locally until communications are restored, ensuring no data is lost.
The Connect system can also send e-mail warnings when alarm limits are
exceeded.
Working With the Data
Using Tinytag Explorer, data recorded by the logger can be viewed as a graph
or as a table of readings. There are also summary views containing
information about the recording and a daily min/max view.
Data from multiple devices recording at the same time can be combined into a
single graph.
Graphical data can be exported from the software as an image, for use in
report writing or presentations, or as a data table, for further analysis in third-
party spreadsheet and data base programs.

Mounting Instructions
Reading Specification
Temperature
Reading Range -40°C to +125°C x 4
Sensor Type Thermistor (external probe)
Logger Resolution 0.02°C or better
Temperature Stability ±0.01°C/°C change from 25°C
Logger Accuracy
The graph below is the accuracy of the TE-4024 when used with a Tinytag
Thermistor probe.
This data logger will turn on and start recording as soon as it is plugged into a
Power over Ethernet (PoE) supply (it can also be turned on before that by
pressing and holding the logger's Mute button briefly) .
Logging Interval 2 minutes to 10 days
Default Logging Interval 10 minutes
Logging/Off-line Capacity 361 days typical, at a 10 minute
logging interval
The logging/off-line capacity for a data logger, for any given logging interval, is
stated at the bottom of the configuration page in Tinytag Explorer when the
logger is programmed.
Standalone Mode
If being used as a standalone device, the logger should be launched using
Tinytag Explorer to ensure its clock is set correctly.

Connections
Power Information
This logger is a PoE (Power over Ethernet) device that is powered from its
Ethernet connection (a PoE injector is supplied).
In the event of a failure of the PoE supply, the logger has a battery back-up
that will keep it recording (communications will be suspended until power is
restored).
Back-up Battery Power
Battery Type 2 x Duracell Industrial ID1500
AA (LR6) 1.5V (supplied)
The logger will operate with other AA cell batteries but performance cannot be
guaranteed.
When the logger’s back-up batteries start to run flat, the LED on the front of
the logger will flash red. If being used as part of a Tinytag Connect system, a
low battery warning will be displayed in the Tinytag Explorer Connect software.
The low battery warnings will start to show when the logger has approximately
two weeks of battery power remaining.
Before replacing batteries the logger must be disconnected from the LAN and
turned off.
Alkaline batteries should always be replaced in pairs.
Data stored in the logger will be retained after its batteries are replaced.
Alarms
External Alarm Output
Warnings
• The alarm cable and connector must not be connected to any voltage
more than 50V away from earth potential, including mains voltages
• Maximum current through any connection: 200mA
• Maximum voltage on the Signal output (relative to Ground): 30V
The alarm output has a signal line that changes state when alarms are active
and it can also supply power to an external device.
Connection Information
An output cable (part number CAB-0041, supplied separately) is used to
connect the logger to an external device.
The wiring connections are as follows:
Both the Power (brown) and Signal (white) outputs are protected by a 350mA
self-resetting fuse.
Signal Specification
This is an open-drain output that is pulled to Ground when an alarm is active
(otherwise it is open-circuit). This output will continue to change state, in the
event of an alarm, should the PoE supply to the logger fail.
Note that muting the internal alarm sounder, by pressing the mute button
on the front of the logger, will also turn off the output. If required, the
connection should be held on (latched) by external equipment until it is
explicitly acknowledged.
Power Specification
The power output is regulated at 11·5V ±0.5V from the PoE supply. The output
voltage will therefore turn off if the PoE supply fails.
Colour Connection
Brown Power
Green Ground
White Signal
LAN data loggers can be programmed with alarm limits to warn when a
property has gone out of specification.
Alarms 2 fully programmable, latching alarms
(per channel)
Alarm Delay 1 second to 10 days
Alarm Indicators Visual (LED) & audible (sounder)
Alarm Output 3-pin, powered output that changes state
when alarms are active (see below)
Tinytag Connect
When used as part of a Tinytag Connect system, an on-screen alarm
indication is also shown in the Tinytag Explorer Connect software.
E-mail warnings can be sent from the Tinytag Connect system when alarm
limits are breached, and these in turn can be used to send SMS messages
using third-party messaging services.
