Poseidon 2251 Temp/Humidity Logger
Description
The Poseidon model 2251 is an industrial grade Ethernet based stand-alone device which can send an email alarm when monitored temperature or humidity sensors exceed their defined range. The 2251 can also record data values in internal memory for download at a later date. Up to 42 sensors can be connected, and these can be up to 1km away from the unit. The Poseidon 2251 also has 3 dry-contact inputs which can also be used to generate alarms. Sensor monitoring and configuration is available via a web-based graphic interface or data can be viewed via several network protocols such as SNMP, XML, and Modbus/TCP.

Description
The Poseidon 2251 is a simple Ethernet based stand-alone device which can send an email alarm when up to 42 monitored temperature or humidity sensors exceed their defined range. These sensors are connected on 2 seperate buses: up to 10 1-wire sensors can be located up to 10m from the unit, and up to 32 industrial sensors can be connected via a RS485 network. These can be located up to 1km from the 2251. 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 at a later date. Logging continues even when the device is not connected to a LAN. The 1250 also has 3 contact-closure inputs which can be used to trigger alarms on state change. Once the Poseidon 2251 is connected to the Ethernet, you can run the free UDP setup utility, which will serch the LAN to find all attached devices. You can then specify your desired Network address parameters. Once this is done, you can simply acces the I/O data from a web browser. There is also a flash-based version. You can assign a name to each sensor and also define high and low alarm limits. When the parameter goes outside these limits, the Poseidon 2251 can send user defined email alarm messages.
All sensor's values as well as alarm status information are available from XML files (temper.xml) and any application can log it from XML tags. The Poseidon 2251 also supports the Modbus TCP protocol, so it is easy to integrate with common SCADA packages such as DAQFactory Typical Applications Pharmacies: monitoring and recording of pharmaceuticals storage temperature Bakeries: monitoring and recording of production processes temperature Freezers: temperature monitoring and recording Food processing: monitoring and recording of values during technological processes, data for HACCP Air-conditioning: long-term monitoring of system setting Storages: technological temperature monitoring of temperatures, humidities and conditions Large buildings: optimising of heating and air-conditioning SCADA systems: connecting of external sensors inputs

Software Applications
nmsDashboard nmsDashboard utilises standard TCP/IP and application protocols to query and monitor network devices and their associated services. nmsDashboard is designed to provide the user with a simple yet powerful mechanism through which they can observe the activity on and respond to alarms raised from their network 24 hours a day, 7 days a week. Free 3-sensor verson supplied with the Poseidon 3265.
CapTemp Simple to use Data Logging and Alarm software package for use with all Poseidon units. Sensor information can be desplayed in both numeric and graphical formats. Data from several Poseidon units can be logged to a single Excel-compatible data file.
DAQFactory Control and monitoring software DAQFactory can be used with the Poseidon 3265 with version that have the connectivity pack. Uses the Modbus TCP protocol. DAQFactory can be used to create an opertor interface, with plant mimics, chart recorders, provide automatic control, PID loops, alarms and datalogging and reporting functions.
