The dataTaker DT4CEM20 is a powerful channel expansion module designed to significantly increase the input capacity of dataTaker DT80 and DT85 series loggers. Each CEM20 unit adds 20 universal analog input channels to one analog slot on a logger, enabling large-scale installations with hundreds of inputs.

Key features include:

• Adds 20 analog channels via one analog channel on the logger — enabling expansion up to 300 inputs for DT80 and up to 960 for DT85.
• Low power consumption: about 0.36 W at 12 V (≈30 mA) during sampling.
• Rugged construction: anodised aluminium case, powder-coated steel end plates, wide operating temperature range (-45 °C to +70 °C).
• Easy connection: powered by logger’s 12 V output; analog output ties into one logger channel. Max distance from logger to last CEM20: 100 m.

Whether you’re expanding a large sensor network, building a structural monitoring array, or equipping an industrial process with hundreds of analog inputs, the DT4CEM20 delivers scalability, ruggedness and cost-efficient expansion.
