Logging of temperature and humidity values, actual values can be downloaded over net (WEB, XML, Email, CSV). To save data it is not necessary working net, power supply is sufficient. You can import the saved data to Excel, for example.
The Poseidon model 2251 logs periodically values from connected sensors into internal Flash memory. It is possible to import the saved values into database or as a Excel file. It alerts to crisis events (temperature out of range, disconnected contact) via email.
- The device saves values even in case the network is not connected or does not work.
- The Poseidon 2251 synchronizes internal time over the network and keeps it for 2 weeks without power supply.
- We guarantee 10 years of data storage period.
Automatic sensor detection configures user over web interface as well as sensors names, saving period.
- SMS can be sent as alarming via GSM modem connected to RS-232
- 3 inputs to connect sensors of brake-type.
- IT bus - up to 10 sensors in budget-prices design (temperature /humidity) over up to 10m.
- Industrial bus - up to 31 sensors in industrial design (temperature, humidity, voltage, current) over up to 1000m.

What measures the Poseidon
 The Poseidon model 2251 supports up to 42 sensors to monitor temperature, humidity, air-flow and other quantities. Each sensor monitors keeping the range of values. It notifies of exceeding range (Alarm state) via Email.
- Temperature (up to 42 sensors, up to 1000m, -55 °C ..
+640 °C)
- Humidity (up to 25 sensors, up to 1000m)
- Digital input/contact (up to 3 smoke detectors, shake, motion,
flooding, angle, door close/open, air-flow etc.)
- General input (0..10V, 4..20mA – with external converter over RS-485)
>> Value sensors
Special features of the 2251 model
 Up to 42 sensors can be connected to one Poseidon 2251 unit over 2 busses.
- Wide sensors assortment, from inexpensive for household use to industrial sensors with 0.15 °C accuracy and -55 .. +640 °C operating range. (see. Value Sensors). Sensors can be connected over up to 1000m.
- No server nor PC is necessary to log values, power supply is sufficient.
- Built-in graphic WWW interface to configure and monitor values - screen shots
- Open communication protocols (WEB, Email, XML, Modbus/TCP)
- Notification of Alarm via Email over SMTP interface
- The Poseidon 2251 directly controls two external relays
- One of outputs can be used as a local Alarm signalization.
- Safety protected by password, IP range, HW protection against configuration changes
- For
 OEM partners, from 50 pieces and more, device name change is possible as well HTML design, contact list etc.
- Collaboration with most of SCADA systems (OPC server and I/O server over Modbus/TCP)
- Software and application:
- Supplied SW: Package of supporting programs and utils (UDP Config, PN Eye, Pos-Excel, PD Trigger and others)
- Development support: SDK (Software Development Kit) development libraries + examples (VB, Delphi, C, C#, etc.)
- Third parties SW application:

Topology
- WEB (HTML)
Values and sensor states are displayed on WWW page. The page is automatically reloaded every 5 seconds. Links such as Flash Setup,
update FirmWare and others.
- XML
All values as well as information about alarm states are available .XML file (temper.xml)
and any application can read it from XML tags. ..more information
- Modbus/TCP
Modbus/TCP is industrial standard for input from sensors and SCADA systems.
All values are accessible over Modbus/TCP - ..more information
- Alarms
- Email
In case of contact switch or exceeding of "Safe Range", the sensor get to the Alarm status. To notify of this a Email including alarm status description is sent to configured email address - .. more information

HW interface - sensors connecting
Overview of all sensors in our assortment: Sensors and accessories
- Binary Input (Dry Contact inputs)
3 inputs to connect door contact or relay output (NO or NC)
- IT Bus (RJ12 1-Wire)
Inexpensive interface to connect up to 10 temperature probes over a total distance of 10 meters or less
- Industrial bus (RS-485)
Industrial interface, up to 31 sensors up to 1 000 meters. The temperature, humidity and other sensors. The converters to current loop (4 to 20 mA) or platinum temperature sensors Pt100, Pt500, Pt1000 (2,3 or 4 conductor)
>> Poseidon sensor interface
HW interface - relay output
- 2 relay outputs
The Poseidon model 2251 supports two outputs for two external relay controlling. The outputs can be controlled over network (Flash Setup, XML).
- Output – Alarm status link: DTR output can be used for alarm signalization of any sensor. Warn light or horn can separately, independently on other software, signal critical status.
We recommend to use: PowerEgg, P1250 RC (Relay Cable), DIN relay

PD Trigger application example
With the PD Trigger application for Windows, it is possible to receive alarms (SNMP traps) from an unlimited number of Poseidon products and define conditions and actions based on the originating device and the probe name. For example:
- In case of air conditioning failure in server room A, send a SMS to Peter
- In case of alarm in server room B, send e-mail to Tom
- In case of electricity supply failure anywhere, send SMS to Peter and turn on a warning light at the receptionist's desk
