Features

  • Allows connecting additional sensors to Vaisala Data Management Unit DMU801
  • Sophisticated, software controllable sensor power control
  • Heating power connection with overcurrent and surge protection (surge protectors on baseboard)
  • 3 isolated RS ‑ 485 ports
  • 1 multipurpose port that supports 2‑ wire RS‑ 485, RS‑ 232, and SDI‑ 12
  • Rugged lightning surge protection for all sensor connections For serial sensor interfaces Vaisala Serial Module DMS801 provides interfaces for serial sensors. With 3 isolated RS‑ 485 ports and 1 multipurpose port, each DMS801 allows connecting 4 additional sensors to Vaisala Data Management Unit DMU801. Depending on the size of your DMU801 base unit, you can connect up to 8 DMS801 serial modules to the system. Rugged solution with internal protection DMS801 operates in a wide temperature range and withstands fast temperature changes. Because of its internal rugged surge protection (up to 3 kA), external surge protection is not required. Easy expansion when needed DMS801 is easy to install during initial system setup and can also be plugged in later to expand the selection of sensors. DMS801 can be configured with the intuitive, node‑ based Vaisala DMU801 Configuration Tool. Vaisala Serial Module DMS801 extends the number of serial ports in Vaisala Data Management Unit DMU801. Each DMS801 provides interfaces for 4 serial connections.
