• Warning message via SMS / eMail and status on web server
The Telemetrylogger type 255U is made of a robust and waterproof aluminum housing. The device can also be used outdoors and without other protective housings, for example in a well house, to measure spring discharges, for surface water applications by connecting different types of sensors, for the data acquisition of precipitation sensors and many others.
Your application, in particular connected sensors, individually required data formats or the selection of the power supply, be it battery operation, with solar support or mains supply, we specify the device exactly to your requirement. You get a fully operational device that fits your needs perfectly. This logic extends through to the operating program. You won't have long and complicated menu structures where you need to engage yourself with technical features what you do not really want. The operating program recognizes the requirements and sensors, you only configure what you really need.
Integrated is a universally applicable analogue input channel, which is ready for use to the requirements for sensors with 0/4 ... 20 mA output, voltage output 0 ... 1/10 volt or as a pulse counter. In addition, an input channel is provided for the connection of up to 4 HT sensors, which are addressed via the integrated modbus protocol.
Via an additional contact connection, alarm messages can be issued via SMS / eMail. This can, for example, monitor a door contact or similar.
Also, the Telemetrylogger type 255U can be equipped with a comprehensive alarm message management, alarm messages can be issued universally and according to your requirements.
