Data Acquisition


  • 3-Axis Encoder Inputs
  • 1 MHz Input Rate
  • 32-bit Count Range
  • Quadrant, Pulse/Dir, CW/CCW
  • 2500 Vrms Optical Isolation
  • Built-in Dual Watchdog


The I-7083 and I-7083B are 3-axis high speed encoder modules. Each axis on the module can be independently confi gured as one of Quadrant, Pulse/Dir or CW/CCW input mode with a maximum input rate of 1 MHz. The high-end specifications of the I-7083/I-7083B and complete software support make it ideal for a wide range of applications in position measurement of motion systems working in industrial and laboratory environments. The I-7083B is an improved version of I-7083 with virtual battery backup function for counter value.
