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analogue inputs

• 4AOmodule with 4analogue 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.
