WebLog 250

The New Generation

M-Bus Datalogger for 250 devices with touchscreen and web server

The new web connectable central unit with touch screen and 1GB memory fits as flexible to your needs as no Relay data logger did before. The WebLog 250 is able to drive 250 meters and manage up to 1000 meters.

The internal database allows you to organize the M-Bus data in a structure which fits your requirements. Another convenient feature is the automatic export of data via email or FTP upload. In addition to the standard interfaces (USB, RS-232C, Ethernet) the customer can also add a WiFi option.

Operation and Features

The WebLog is operated by the 7“ wide LED touch screen or with your PC / Laptop via the web browser. The logged data can be exported to an USB flash drive, FTP server or via email to csv, xlsx or xml files. Two inputs for potential-free contact (status indicator) and three relay outputs complete the functionality of the WebLog. By the built in universal power supply (110-250 V AC) and the robust ABS plastic housing with separate terminal compartment, it adapts also perfectly to the requirements of the installation practice.

Mounting can be done either on a DIN rail or on the wall. By an optional cylinder lock the device can be secured from unauthorised access. In order to complete the functionality of the WebLog, the software allows a structured user management with different access rights and the management of multiple meter groups and different reading intervals. In addition you can always choose between the implemented languages for the user interface. Installation and configuration of the WebLog central unit is made much more easier by a built in wizard, that guides you step by step to the finished installation. Additionally the WebLog 250 can be use as an transparent level converter via USB or RS232C.
