An article in the form of a module in its own housing with dimensions of approximately 11 × 7 × 5 cm (so-called ‘analogue input module’).
The module consists of two printed circuit boards comprising an input interface with four channels, an analogue-to-digital converter, a processor and a bus interface for connection to a programmable logic controller (PLC). The module has an input voltage range from 0 up to 10 V DC.
The module receives analogue signals representing, for example, measurements of temperature, speed, flow or weight from various external devices.
The module converts and processes these signals before sending them to the PLC.

Classification is determined by General Rules 1 and 6 for the interpretation of the Combined Nomenclature, Note 2(b) to Section XVI and the wording of CN codes 8538, 8538 90 and 8538 90 99.
As the module constitutes an interface between external devices and a numerical control apparatus of heading 8537, classification under heading 8471 as an input unit is excluded.
As the module receives, converts, processes and sends electrical signals to the PLC, classification under heading 8536 as a switch or a relay for making connections to or in electrical circuits is excluded.
As the module does not control external devices by itself, but only constitutes the interface between such devices and the PLC, classification under heading 8537 as an electric control apparatus is excluded.
As the analogue-to-digital conversion is only an intermediate process, classification under heading 8543 as electrical machines and apparatus, having individual functions, not specified or included elsewhere in Chapter 85 is excluded.
Since the intended use of the module is to receive, convert and process signals representing measurements received from external devices and send them to the PLC, the module is essential for the operation of the PLC of heading 8537.
The article is therefore to be classified under heading 8538 as parts of apparatus of headings 8535 to 8537.

An article in the form of a module in its own housing with dimensions of approximately 11 × 7 × 5 cm (so-called ‘discrete output module’).
The module consists of a printed circuit board comprising a bus interface for connection to a programmable logic controller (PLC), a processor, a digital-to-analogue converter and an output interface with 8 connecting points.
The output connecting points are relays of the electromagnetic type with an output voltage range from 0 up to 250 V AC and a load current per point up to 0,17 A.
The module processes and converts discrete signals representing an On/Off signal (for example, 1/0 or True/False) before sending them to various external devices, such as contactors, relays and indicator lamps.

Classification is determined by General Rules 1 and 6 for the interpretation of the Combined Nomenclature, Note 2(b) to Section XVI and the wording of CN codes 8538, 8538 90 and 8538 90 99.
As the module constitutes an interface between external devices and a numerical control apparatus of heading 8537, classification under heading 8471 as an output unit is excluded.
As the module receives, processes, converts and sends electrical signals to external devices, classification under heading 8536 as a switch or relay for making connections to or in electrical circuits is excluded.
The output connecting points (constituted by electromagnetic relays) are only a part of the module which consists, in addition to the connecting points, of the bus interface, the processor and the digital-to-analogue converter. Moreover, the module does not control external devices by itself, but only constitutes the interface between the PLC and such devices. Classification under heading 8537 as an electric control apparatus is therefore excluded.
As the digital-to-analogue conversion is only an intermediate process, classification under heading 8543 as electrical machines and apparatus, having individual functions, not specified or included elsewhere in Chapter 85 is excluded.
Since the intended use of the module is to receive, process and convert signals representing an On/Off signal received from the PLC and send them to external devices, the module is essential for the operation of the PLC of heading 8537.
The article is therefore to be classified under heading 8538 as parts of apparatus of headings 8535 to 8537.
