Overview
The CDM-A116 is an analog input module that allows you to easily expand your Campbell Scientific data logging system. The CDM-A116 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-A116 has 16 differential inputs and four excitation channels. It provides two 12 V ports and two switched 12 V ports for powering your peripherals, as well as four switched 5 V ports for peripheral control.
Key Advantages
Greatly increases sensor capacity
Technical Description
The CDM-A116 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
- Ability to make simultaneous measurements
- CANbus 2.0A/2.0B capable; contact Campbell Scientific for details
