Datasheets

The M series carries up to four independent radio signals from the safe area to antennas in the hazardous area with a single Ex ia associated apparatus. It is designed for control rooms, cabinets and Ex p panels, where radios and modems stay in the safe area and only the antennas go into the field.

Key features

  • 2, 3 or 4 independent RF channels in a single device
  • 300 MHz – 9 GHz band, RF power up to 7 W per channel
  • Wall or DIN rail mounting inside the panel
  • Non-Ex antennas in Zone 0/1/2 and 20/21/22 thanks to the [Ex ia] output
  • Antennas removable while energised
