Stratus Modbus Logger

Uses GPRS/EDGE/3G GSM (UMTS/HSPA) technology.

Bluetooth interface — setup and manual data collection can be achieved through the Bluetooth interface negating the need for cables that invariably fail during continuous use.

Battery or external 12V power with battery failover in dual mode.

Uses 3x standard D Cell alkaline batteries that can last in excess of 5 years under normal usage. Many other loggers use lithium batteries that are expensive and difficult to obtain. Other problems involving lithium batteries are the restrictions when shipping using airfreight. All lithium batteries need to be shipped as hazardous cargo that is becoming increasingly difficult to achieve as many airlines are no longer allowing these batteries on their aircraft.

Isolated 4-20mA interface. Used for any sensing device with a 4-20mA output.

Onboard 24V 30mA power generator. The Stratus Modbus logger can generate a stable 24V output at a maximum of 30mA allowing for the powering of an external piece of equipment or current loop device eliminating the need for a secondary power supply. This option will also function under battery operation.

RS485 Modbus Port (2-wire).

Large onboard non-volatile memory — This logger can record up to 20000 records (application specific) for later download.

Logging intervals from 1 minute to 1 month. Information is internally logged, time and date stamped and transmitted at programmable intervals.

Remote programming of all setup parameters via GSM link or SMS.

Ideal for leak detection, alarming and water shut-off control to prevent water loss.

Onboard Bluetooth can stream diagnostic information about signal strength, network status etc.

Touch sensitive button and LED's for manual wakeup to server and diagnostic purposes are accessable on the outside without the need for opening the housing.

Available with the standard internal antenna or a connector (SMA) for an external antenna. Note that the external connector will affect the IP rating.
