3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not take into account any unforeseen circumstances and events which occur
during installation, operation and maintenance. The operator is responsible for observing the location-spe-
cic safety regulations, also with reference to personnel.
Generalhazardoussituations.
To prevent injuries, observe the following:
▶Do not modify the device.
▶Do not mechanically load the device.
▶Secure the device or system to prevent unintentional activation.
▶Only trained technicians may perform installation and maintenance work.
▶Install the device according to the regulations applicable in the respective country.
▶After an interruption in the power supply, ensure that the process is restarted in a controlled manner.
▶Observe the general rules of technology.

Product description
TypeME44
5 PRODUCT DESCRIPTION
The I/Omodule TypeME44 receives measurement data from external sensors and inputs, converts them,
and forwards them to external actuators or büS participants and gateways to controllers, and is also
capable of issuing data from controllers or büS participants.
The I/Omodule TypeME44 is available in the following variants:
• 4AImodule with 4analog inputs
• 4AOmodule with 4analog outputs
• 8DImodule with 8digital inputs
• 8DOmodule with 8digital outputs
5.1 Possible combinations
The I/Omodule TypeME44 can be used as part of a system in combination with other modules. To
assemble a system consisting of multiple modules, contact your Bürkert sales department.
Example of a system at the minimum conguration level:
