CDM-A116 Módulo entradas analógicas 16 canales diferenciales
Services Available

Resumen

El CDM-A116 es un módulo de entradas analógicas que permite fácilmente expandir el número de canales de entrada analógicos de nuestros dataloggers Campbell Scientific. El CDM-A116 contiene un conversor A/D de 24-bit, y un front-end de bajo ruido que proporciona medidas analógicas excepcionales. Este módulo permite también promediar períodos y dispone de canales de excitación en voltaje y corriente para alimentar puentes de medida.

El CDM-A116 tiene 16 canales de entrada diferenciales y 4 canales de excitación. Dispone de terminales 12V, dos de 12V conmutables para alimentar periféricos, y cuatro terminales de 5V conmutables para control de periféricos.

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
