The VOLT 116 is an analog input module that allows you to easily expand your Campbell Scientific data acquisition system. The VOLT 116 has 16 differential or 32 single-ended input channels 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. The VOLT 116 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.

Benefits and Features

  • 24-bit ADC and low-noise analog inputs
  • Channel count expansion via the CPI bus
  • Scales up the number of channels without adding measurement time
  • Easier to program than multiplexers
  • Programmable noise rejection
  • CANbus 2.0 A/B output available
  • USB 2.0 interface for PC-based operation
