Benefits and Features

  • Can be added to or removed from CR9000X to support changing measurement needs
  • CR9055EC disconnects sensors easily so CR9000X can be moved from location to location
  • Measures voltages up to ±50 volts


Detailed Description

The CR9055E is an I/O module for the CR9000X-series and CR9000-series dataloggers. It contains 14 differential (28 single-ended) input channels for measuring voltages up to ±50 V. The resolution on the most sensitive range is 16 microvolts.

The CR9055E includes one CR9055EC easy connector module. Easy connector modules allow sensor wiring to remain connected while the input module’s measurement electronics and the rest of the datalogger system are used elsewhere. Additional CR9055ECs are purchased as a separate line item.
