w .moxa.com ioPAC 8500 Series (85M) Modules Rugged modules for the ioPAC 8500 Series Features and Benefits

  • Compliant with EN 50121-3-2, EN 50121-4, and a portion of EN 50155 specifications
  • Rugged and compact design for harsh environments
  • Expand the I/O and communication capabilities of your ioPAC 8600 or 8500 Series device
  • Wide operating temperature range: -40 to 75°C (-40 to 167°F)
  • Millisecond timestamp granularity for digital input and analog input
  • Supports sampling rates up to 40 kHz for analog input
  • Pre-recording for analog input data logging
  • Up to 4 3-in-1 RS-232/422/485 serial ports Certifications Introduction Moxa’s ioPAC 8500 Series 85M Modules can be installed in both ioPAC 8500 and ioPAC 8600 Series devices. Modules are available with DI/Os, AIs, Fast AIs, and serial interfaces, giving users a wide variety of options to choose from and allowing them to select the I/O combination that best fits their target application. All 85M modules are designed for railway industry applications, and as such, are compliant with EN 50121-3-2, EN 50121-4, and a portion of the EN 50155 specifications. In addition, these modules all support a wide operating temperature range of -40 to 75°C for reliable operation even in harsh environments.
