GM10 Modular Data Acquisition & Logging System

Yokogawa has worked to develop a full Data Acquisition System, a group of tools utilized to measure electrical and/or physical events.
The GM10 modular data acquisition and logging system utilizes an expandable housing linked to the module base. This design enables the use of a wide range of I/O modules, which can be expanded by one or more at a time. This data can be logged and changed in real time without additional software.
  • Modular housing for up to 10 I/O modules per GM10 unit
  • Measurement capability of up to 420 actual input channels in a multi-unit configuration
  • Internal memory of up to 1.2 GB
  • Installation flexibility (no attachments required)
  • Open front panel for easy insertion or removal of modules
  • 4 alarms per measurement channel: high limit, low limit, difference high limit, difference low limit, rate of change increase, rate of change decrease, delay high, delay low
