CR9058E 60 V Isolated Analog Input Module with RTD and CR9058EC
Services Available


The CR9058E is a ±60-volt input module for the CR9000X and CR9000 measurement and control systems. The CR9058E has 10 differential inputs. Each channel has its own isolation ground, which can be used to connect a shielded cable. The CR9058E has an on-board resistance temperature detector (RTD) to provide a reference temperature measurement for thermocouple measurements. It ships with one CR9058EC Easy Connector Module.

Benefits and Features

  • CR9058EC disconnects sensors easily so CR9000X can be moved from location to location
  • Can be added to or removed from CR9000X to support changing measurement needs


Detailed Description

The CR9058E is an I/O module for the CR9000X-series and CR9000-series dataloggers. It contains 10 isolated differential channels and an internal RTD. The differential channels are used to measure thermocouples or other devices that have a low level voltage output. Each channel has its own isolated ground for connecting a shielded cable, and its own 24-bit A/D converter that supplies input isolation for up to ±60 Vdc. An internal digital signal processor filters noise. The module's RTD typically provides the reference temperature for thermocouple measurements.

The CR9058E includes one CR9058EC easy connector module. Easy connector modules allow sensor wiring to remain connected while the input module’s measurement electronics and the rest of the data logger system are used elsewhere. Additional CR9055ECs are purchased as a separate line item.
