CDM-A108 8-Channel 5 V Analog Input Module

24-bit resolution, greatly increases sensor capacity

9 ₫

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 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 12 V and a switched 12 V port for powering your peripherals and two switched 5 V ports for peripheral control.

Category:

The CDM-A108 offers 24-bit sigma-delta Adc with 16 user programmable notch frequencies from 30,000 Hz to 2.5 Hz, including 50 and 60 Hz. Previous generations of data loggers could notch out 50 or 60 Hz.

Benefits and Features
