CDM-A116 16 通道 5 V 模拟输入模块
Services Available

概览

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.

优势与特点

  • Ability to make simultaneous measurements
  • CANbus 2.0A/2.0B capable; contact Campbell Scientific for details

技术说明

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.

CPI Calculator v.1.0 (2.49 MB) 06-07-2016

The CPI Calculator is a downloadable Microsoft Excel spreadsheet used to estimate the usage and capacity of a CPI network.  The calculator provides an overview on CPI devices including the CDM-A108, CDM-A116, CDM-VW300, CDM-VW305, and the CSAT3B.  The calculator can also estimate the measurement speed of the CDM-A108 and CDM-A116 based on the number of channels and measurement parameters.

 

The CPI Calculator is an estimation tool and will help you better understand and design CPI networks by considering the following:

  1. What is the capability of each CDM or CPI device
  2. What is the CPI network capacity
  3. How much of the CPI capacity are the CDMs or CPI devices using
