Technical Specification:

  • Supports up to 3 HART channels.
    • HART can be used as a primary or secondary master.
  • The HART interface supports point-to-point mode and multidrop mode.
    • Point-to-Point mode supports burst operation HART slave device data.
    • Multidrop mode supports the HART-channel.
    • Using internal resistor connects at most 13 HART devices (270Ω) if port is ON.
    • Using external resistor connects up to 15 HART devices (250Ω) if port is OFF.
    • Note: The actual maximum number of connections is dependent on the environment, impedance of communication cables, the minimum operating voltage field instruments, communication distance, etc.
  • Ability to support all commands of the HART protocol.
    • Each HART command can be configured for change-of-state output, polling output, initialization output or disable output.
    • The HART channel supports up to 100 commands. A HART output data buffer is up to 2000 bytes and a HART input data is up to 3000 bytes.
    • Supports long frame format.
  • Automatic baud rate detection on Ethernet (10/100M), ability to support IP address conflict detection, automatic routing functions.
  • Supports 36 Modbus TCP connections and up to 512 command requests at the same time.
  • Easy configuration with free SST-HE-CFG software tool.
  • Operating Temp: -40°F to 158°F (-40°C to 70°C); Rel. Humidity: 5% to 95% (non-condensing)
  • Dimension (W*H*D): 1.57in*4.92in*4.33in (40mm*125mm*110mm).
  • Mounting: DIN Rail Mounting (35mm).
