Online help for 4-Channel Data Logger

General product information

The 4-Channel Data Logger is a data logger designed for stand-alone operation. It is used to determine, process and transmit analogue and digital signals. Thanks to the 4 universal inputs, which can be operated in different analogue and digital modes, the 4-Channel Data Logger is compatible with a large number of different sensors. The sensors can be connected directly, without additional energy sources. The energy supply is then provided from the 4-Channel Data Logger , which, depending on the power supply unit used, can itself be operated without mains supply. In addtition to the switchable and selectable sensor supply, the 4-Channel Data Logger is also equipped with an isolated switch contact and a switchable 3,3 V supply. These can be used to control actuators. An interface for connecting a PT100 or PT1000 is moreover available following the chargeable release. By using the mobile network to transfer data to the server, the site rarely has to be physically accessed and the data can be accessed at all times.

Connection examples (digital, open collector output, 0/4...20 mA, 0...2/10 V)

1 Main terminal block of the 4-Channel Data Logger 4 2-wire mA sensor
2 Isolated relay contact 5 3-wire mA sensor or 3-wire U-sensor
3 Sensor with open collector output    

Connection examples (active mA output)

1 Main terminal block of the 4-Channel Data Logger 2 Active mA output, transducer or isolation transformer

A detailed explanation is provided in section Connecting the sensors, actuators and power supply.

Activate transport mode by setting the "operating mode" in the "Basic settings" configuration section (see Basic settings) to "transport". After that, initiate a connection (see Aloha transmission mode) to transmit the changed configuration to the 4-Channel Data Logger .

A detailed explanation is provided in section Storage of the product.
