The Channel Expansion Module (CEM-AD) is constructed on one printed circuit board, which is mounted into a module chassis. This chassis has the same footprint size as the dataTaker data logger modules.
Note: The dataTaker 50 does not support the Channel Expansion Modules.
The Channel Expansion Module (CEM-AD) printed circuit board comprises
the analog input channels, and relay multiplexers
digital input/output channels
a regulated 5 volt sensor power supply
ground and external reference terminals
A male 25 pin plug for connection to the dataTaker 500/600 series loggers
A female 25 pin socket for connection to other Channel Expansion Modules
All signal input and output connections of the Channel Expansion Module (CEM-AD) are made by screw terminals arranged along the edges. The input and output channel numbers are labelled adjacent to the screw terminals.
Figure 5 illustrates the layout of all terminals and connectors of the Channel Expansion Module (CEM-AD).
The Channel Expansion Module (CEM-AD) is normally supplied in the basic format as a free standing module, and can be used in this format in work rooms, laboratories and other clean areas.
Alternatively the Channel Expansion Module can be mounted with the dataTaker data logger into enclosures to suit the particular application, eg. heavy duty industrial enclosures, weatherproof enclosures, portable carry cases, etc.
A variety of enclosures are available from your dataTaker supplier, for industrial, weatherproof and portable applications.
The Large Industrial Enclosure (LIE) will house 1 dataTaker and 1 Channel Expansion Module, and the Small Industrial Cabinet (SIC) will house 1 dataTaker and 2 Channel Expansion Modules.
