2108 Analog Output Module​

Easy interfacing from 2100 Series to SCADA/DCS

2108 Analog Output ModuleThe 2108 Output Module provides three independent current outputs for ISCO 2100 Series Area Velocity Flow modules; the 2150, 2151, and 2151P. The 2108 is DIN Rail mounted and uses a 7-26V DC power supply. 

It provides an easy interface from ISCO’s advanced 2100 Series Area Velocity Modules to data collection systems like SCADA/DCS or any other secondary instrument systems.


When you purchase instruments from Teledyne ISCO, you not only receive innovative, high quality products, you also receive excellent customer service and product support. Your initial purchase is only the beginning of Teledyne ISCO's ongoing commitment to their customers.

Standard Features

  • Three independent, isolated outputs per module.
  • Outputs are freely programmable for any parameter measured by ISCO’s Area Velocity flow module.
  • When more than one module is stacked, each output can be configured for any parameter for any module connected to the 2108.
  • The 2108 Module can be mounted as far as 3,000 ft from other modules (an ISCO Quick Disconnect is recommended to simplify the installation).
  • ISCO Flowlink 4.15 can interrogate any 2100 Series module through the 2108, eliminating the need for confined space entry.


  • Interfacing 2100 Series (2150 or 2151 flow modules) to SCADA systems and other analog data applications

Options and Accessories

  • DIN rail mount DC power supply. Input 115-230 VAC 50/60 Hz, Output 12 VDC, 1.5A.
  • 2100 Series Connect Cable, 50 ft. (15 m). One cable end has a single connector to plug into bottom of 2100 Module. Opposite end is unterminated with six wires stripped for connection to 2108 Analog Output module, Quick Disconnect box, or other device.
