H50 compact telemetry station

The telemetry station in a stainless steel housing with a diameter of 50 mm is conceptually based on the proven mechanical design of the STELA station.

The housing diameter allows the H50 station to be powered by a pair of ER34615M lithium batteries, which can be easily replaced by the user.

Unlike the H40 or STELA stations, the new H50 station does not need a cable connection to a PC for local communication with the user, because it uses a power-saving Bluetooth BT5 interface with a long range of tens of meters. On the user side, communicating with the device requires installing the FIEDLER CONNECT app on a mobile phone, which can be downloaded from Google Play.

The station communicates with the server via a built-in GSM module, just like other telemetry stations. The station can also be configured remotely via the server. Data collection runs over the NB-IoT network, with GPRS serving as a backup.

Inputs: the unit is fitted with a 7-pin connector for connecting a sensor or measuring probe. The connector provides an RS485 bus (FINET or MODBUS protocols), one 4-20 mA analog input and two pulse/binary inputs. In addition, the connector also includes a user-adjustable output supply voltage for the connected sensor/probe.

Alternatively, instead of the RS485 bus, the input connector can be fitted with an SDI-12 serial communication line and two analog inputs.

The H50 station includes self-diagnostics that continuously monitor the condition of the power batteries, the current drawn by the connected sensor/probe, the humidity and temperature inside the device, and several other quantities which, if they exceed a set limit, can trigger an extraordinary data transmission to the server, alerting the user to the problem.

Total number of recording channels: 8 analog, 2 binary, 5 control, 1 text. The control channels record the outputs of the device's self-diagnostic functions.

Data memory capacity: 2048 kB Flash type, 250,000 - 450,000 measured values.

Power batteries: 2 pcs ER34615M.

Mechanical design: Stainless steel housing with a diameter of 50 mm, length 250 mm, IP68 protection
