' =) SCIENTIFIC WHEN MEASUREMENTS MATTER Overview The CDM-A108 is an analog input module that allows you to easily expand your Campbell Scientific data logging system. The CDM-A108 features a 24-bit, analog-to-digital converter and a low-noise, analog front-end to provide you with superior analog measurements. This module also supports Benefits and Features ) Ability to make simultaneous measurements ) CANbus 2.0A/2.0B capable; contact Campbell Scientific for details Technical Description The CDM-A108 offers 24-bit sigma-delta Adc with 16 user programmable notch frequencies from 30,000 Hz to 2.5 Hz, Specifications -NOTE- Additional specifications are listed in the COM-A108 and CDM-A116 brochure. Power Requirements 96 to 32 Vdc voltage Mounting Standard 1-in. grid (DIN rail mounting available) For comprehensive details, visit: www.campbellsci.eu/cdm-a108 o Fet= (o= CDM-A10 8-Channel 5 V Analog Input Module 24-Bit Resolution Greatly increases sensor capacity period average measurements and includes both current and voltage excitation channels. The CDM-A108 has eight differential inputs and two excitation channels. It provides both a 12V and a switched 12V port for powering your peripherals and two switched 5 V ports for peripheral control. ) Increases the number of analog channels in a data logger system ) Supports period average measurements ) Includes both current and voltage excitation channels including 50 and 60 Hz. Previous generations of data loggers could notch out 50 or 60 Hz.
