Intelligent Data Logging Products Features
• Compact size
• Extremely low power
• Cost effective method of adding analog channels to a data logger.
• Each CEM20 multiplexes 20 analog channels into one analog channel on the data logger. Increased channel capacity
Increasing the channel capacity of the dataTaker DT80 range is made very easy by
adding dataTaker Channel Expansion Modules (CEM20). Each CEM20 adds an
extra 20 universal data logging channels to the dataTaker data logger. A dataTaker
CEM20 connects to one analogue channel of the dataTaker data logger.
This effectively expands the total channel capacity of the DT80 to 300 inputs and
the DT85 to an incredible 800 inputs. Incorporating the same duel isolation technology as the DT80 range dataTaker
data loggers each channel of the CEM20 can be used for two isolated inputs or
three common reference inputs so the maximum inputs increases further :- Maximum Input Capacity | | Four wire Isolated Input | Two wire Isolated Input | Two wire Common Reference Input | DT80 | 100 | 200 | 300 | DT85 | 300 | 600 | 800 |
Easy set up and connection
Connecting a channel expansion module to a dataTaker data logger is very easy.
The CEM20 is powered directly from the dataTaker data logger 12V output. Analog
output connections of the CEM20 wired to any analog channel of the data logger.
See sample wiring diagram shown. Solid construction and design
The construction of the CEM20 is similar to the rugged dataTaker DT80 range.
The case is made from an anodized aluminium extrusion with powder coated steel
end plates. Removable screw terminals provide flexible options for installation
and maintenance. Compatibility
The dataTaker CEM20 is compatible with the following dataTaker data loggers :-
dataTaker DT80 Series 2
dataTaker DT80G Series 2
dataTaker DT85 Series 2
dataTaker DT85G Series 2 |
