 2105 Network Interface Module

A powerful solution for flow and parameter data interchange needs

The 2105 Interface Module is a powerful solution for environmental monitoring professionals to interface different monitoring and recording instruments.

The 2105 will monitor the recorded data and take intelligent actions, such as sampler enabling, pacing, and/or alarm generation, based on user-specified conditions.

Its unique flexibility allows connection to several devices at the same time. Isco 2100 Series Flow Modules, Isco’s ADFM pulse Doppler flow meters, 6712 Samplers, 4200 Series Flow Meters, and Isco Rain Gauges are directly compatible. It can also be used with non-Isco instruments that have SDI-12 or Modbus output. Additional input options (4-20 mA, etc.) are possible using readily-available aftermarket converters.

An optional built-in cell phone modem allows remote access to data that has been stored within the 2105, and can fed to a central server via the Internet.

Isco’s modular design allows the 2105 to be stacked with other 2100 Series flow, communication, interface, or display modules.

Standard Features

  • Rugged, submersible enclosure meets NEMA 4X, 6P and IP68 requirements.
  • May be stacked together with up to three other Isco 2100 Modules
  • A variety of factory-available cables allows literally dozens of multiple instrument configuration possibilities.
  • Variable rate data storage lets you change the data storage interval when programmed conditions occur. This feature assures maximum information about an exceptional event - such as an overflow - while conserving power and data capacity during normal conditions.
  • Secure data storage. All data are continuously stored in flash memory to protect against loss in case of power failure
  • Records and stores input voltage and temperature data.
  • 38,400 bps serial port communication provides speedy setup and data retrieval.

Applications

  • Capacity assessments
  • I&I, cMOM, SSO and other collection system monitoring
  • Permit compliance and enforcement
  • Stormwater runoff monitoring
  • Non-point source monitoring
  • River and stream gauging

Options and Accessories
Potential variations for interfacing different hardware and software to make up the comprehensive data system you desire are virtually unlimited with the 2105. Input/output choices are shown in the diagram above - and may be enhanced by using available aftermarket converters.
