Single port Half Duplex RS-485 or Simplex RS-422 with Surge Blocker Technology.
The DSA-01HP features a hybrid of Surge Blocker technology and conventional Gas-Discharge-Tubes.
The Surge Blocker technology will trip in less than 1 microsecond when the surge current reaches 750mA. BFR Digital's Surge Blockers, block surges and provide an effective barrier behind which sensitive electronics will not be exposed to large voltages or currents during surge events. After the surge event, the Surge Blocking Device will automatically reset. The top-end protection is via GDT (Gas-Discharge-Tubes). The DSA-01HP needs an electrical earth connection onto which the surge energy is safely discharged.
