dataTaker - Model CEM20 -Channel Expansion Modules

• Turns one analogue channel into 20
• Cost effective
• Compact size
• Ultra low power
• Compatible with DT80 & DT85 series loggers (series 2 and later)
• Solid construction and design

Increasing the channel capacity of the dataTaker DT80 range is made very easy by adding dataTaker Channel Expansion Modules (CEM20). Each CEM20 connects 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 analog inputs and the DT85 to an incredible 960 inputs. Incorporating the same dual 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.

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 connect to a analog channel of the data logger. See sample wiring diagram shown.

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.

The dataTaker CEM20 is compatible with all variants of the DT80 and DT85 data loggers series 2 and above.
