Boztek Remote Telemetry Solutions are based on the CV3100 RTU. The 3100 is proven technology with over 2500 units now in the field in varying applications since its inception a little over 10 years ago where series one was release as a mobile GSM  unit  later releasing series two for the CDMA network. Today the 3100 has grown to except many protocols and hardware by default with a variaty of wireless medium now being used to move remote data back to base.    


System Features

  • Available for GSM and Next-G mobile and Satellite networks.
  • Full two-way web and SMS access for monitoring and control from mobile phone or PC.
  • Data sent by email or web for continuous data transfer
  • Next-G or GPRS (GSM) options available.
  • Integrated controller, modem, power supply, relays and isolated inputs.
  • Includes web and PC-based configuration and monitoring software.
  • Low power operation – engineered for solar applications.
  • Custom interfaces available for specialised devices, e.g.:Composite temperature /humidity/dewpoint sensor.
  • Rain gauge, wind speed and direction, and soil moisture sensors - Davis and Vaisala Weather Stations
  • Optional on-board GPS.

Controller Specifications

  • Equipment can be started or stopped remotely and analogue setpoints can be set by web or SMS commands.
  • Alarms can be sent to any mobile phone(s) via SMS, or to any PC via the web.
  • On-board switch-mode power supply can accept unregulated 7-40V DC in.
  • 8 x Optically isolated digital inputs (expandable on-board to 16 in) can accept signals of up to 48 V DC.
  • 2 x Analogue inputs @ 0-10 V.
  • 4 x Relay outputs (expandable on-board to 8 out), each capable of switching 5A at 240V AC.
  • Data logging – can store up to 12,000 events, depending on model**:
    • An “event” is any (digital) equipment start, stop, alarm, etc, or any logged analog values.
    • Analogues can be programmed to log on time period, conditional upon minimum % change.
    • ** Model Standard capacity = 2,000 events.
    • ** Model Expander capacity = 12,000 events.
    • Other models available with removable flash storage media.
  • Communications (factory options):
    • “Pass-through” port, configurable as RS232, RS485 or SDI.
    • Two-way translation between Modbus protocol and SMS, for direct interface to industrial controllers.
  • Power consumption in stand-by, with modem powered off, approx. 30 mA
  • Operating temperature: -25 to +70C
  • Humidity 5-95% non-condensing
  • Enclosure Dimensions:  195mm x 125mm x 50mm approx.


Advanced Features

  • • HTTP interface for web-enabled peripherals.
  • • On-board event log – logged data can be displayed graphically.
  • • Configurable “watchdog” function to confirm system operation.
  • • Communications “pass through” option – your SCADA software can share the on-site mobile modem.
  • • Cross dependency of inputs e.g. “pressure fault only examined if pump is running for 30 sec.”
  • • Relay outputs can be controlled by SMS, programmed sequence, and directly from alarm inputs.
  • • Versatile software control, including “one-touch” remote activation of complete control sequences.
  • • Optical isolation of digital inputs – wide input range.
  • • Digital inputs can be configured as pulse-count totalisers or proportional frequency inputs.
  • • Optional ultra-low power digital radio link between modules (up to 5km, depending on terrain).
