The CEM20 Channel Expansion Module provides a simple and flexible way to increase the channel capacity of the DT80 and DT85 data loggers.
Each CEM20 adds 20 universal data logger channels, significantly expanding the number of available analog inputs.
With the DT80, the total number of analog inputs can be expanded up to 300 channels, while the DT85 supports up to 800 inputs.
The module is ideal for large-scale measurement and monitoring applications in industrial automation, environmental monitoring, and process control systems.

Connection to the data logger is established through a digital control connection using 5D and 6D input/output terminals.
Power is supplied through 12V and DGND dual terminals.
Analog connections are available through the terminals *, +, -, #.
The maximum number of supported CEM20 modules is:
- 5 modules for DT80 & DT80G (Series 2)
- 15 modules for DT85 & DT85G (Series 2)
The system uses a relay multiplexer.
The maximum input voltage is 30 VDC.
The maximum sampling speed is 12 Hz.
Power is preferably supplied via the switched 12V output of the data logger. Alternatively, an external regulated 12 VDC ±5% power supply can be used.
