TE-4901
Tinytag Plus LAN Single Input Count Data Logger
(0 to 32,000 counts per interval)
Connections
This logger can be used with a CAB-3246 Tinytag Current/Millivolt/Count Input
Lead (supplied) or an ACS-9700 2-Pin Plug.
The connection details for the cable and plug are as follows:

Alarms
LAN data loggers can be programmed with alarm limits to warn when a
property has gone out of specification.

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.
External Alarm Output
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:

Signal
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.
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
2 fully programmable, latching alarms
1 second to 10 days
Visual (LED) & audible (sounder)
3-pin, powered output that changes state
when alarms are active (see below)
