IridiumLink Logging Transmitter

Sutron is an authorized Iridium Valued Added Reseller. The IridiumLink Provides Complete Two-Way Communications with Remote Stations Anywhere in the World

FEATURES

GUI setup program. 2. Terminal strip with screw terminals for I/O and power connections 3. Operates 8-16VDC — 12V recommended for SDI-12 sensors 4. TCXO real-time clock with battery backup (+/-4ppm) 5. Solar panel regulator for panels up to 30 watts. 6. Support for up to 16 measurements of the following inputs:

  • SDI-12/RS485 (shared as is done in the Sutron Bubbler)
  • 5 Analog inputs:
    • Two (2) single ended inputs (range 0-5V)
    • Two (2) differential inputs (range +/-39mv, +/-312mV, +/-2.5V)
    • One (1) 4-20mA input
  • 2 digital inputs. They can be used for tipping bucket, frequency, and on/off inputs
  • 2 internal SPI for future expansion
  • Internal temperature
  • Battery voltage
  • Meta measurement

Options to average or accumulate 8. Lightning protection (Gas Tube) on all external inputs. 9. User specified equation on any measurement . 10. User specified alarm detection on any measurement. 11. 2 LED for verification/diagnostics. 12. Log capacity of 240K of data accessible via Iridium® and direct connect 13. Switched Battery Output 14. Also operates as a standalone recorder without telemetry 15. USB slave for connection to PC. THE USB PORT WILL NOT WORK with USB devices like memory sticks, modems, etc. 16.
