Vaisala vNet Power over Ethernet (PoE) Data Logger Interface

Features

  • Eliminates the cost of wiring AC power to each monitored point.
  • Data loggers can be installed wherever a LAN cable can be run.
  • Increased data communication protection from power outage because the server room’s UPS can provide backup power
  • Plug and Play connectivity when using viewLinc Aware function.

Dpstar is a leading supplier of environmental measurement sensors for temperature, relative humidity, pressure, dew point, CO2, and other environmental condition monitoring for industrial process application and research. Since the ’90s, we earned a reputation as a trusted partner to our clients through our commitment and dedication. We are an authorized distributor and supplier of measuring sensors solutions from renowned manufacturers Vaisala. Vaisala is a global leader in environmental and industrial measurement. Building on 80 years of experience, Vaisala provides observations for a better world. Vaisala is a reliable partner for customers around the world, offering a comprehensive range of innovative observation and measurement products and services.

Wherever reliable network communications and costs are important, more companies are using Power over Ethernet (PoE) devices. Vaisala vNet PoE network interface brings easy connectivity with Vaisala DL series data loggers at a lower cost than alternative networking devices. The snap-in design streamlines data logger connectivity into a small footprint, eliminating wires between normally separate data loggers and PoE devices. When power and data are carried over the same cable, you can also eliminate the cost of installing an AC power source. vNet PoE integrates VL and SP data loggers without compromising their high accuracy. It brings greater flexibility and simplicity to the deployment of Vaisala Continuous Monitoring system. The viewLinc Aware function in viewLinc monitoring software allows you to quickly configure data loggers, alone or in batches. Simply place data loggers in a vNet cradle, connect to a Local Area Network, and viewLinc discovers and configures the data loggers.

vNet PoE interface comes in four models:

  • CDL-VNET-P with a fan inside the cradle for data loggers with an internal temperature channel.
  • CDL-VNET-LP without a fan for data loggers without an internal temperature channel.
  • CDL-VNET-PC with 15 V output to power external sensors and transmitters; includes internal fan
  • CDL-VNET-LPC with 15 V output to power external sensors and transmitters; without internal fan

There is also an option to power the interface with AC. Select the model that fits your application to monitor and record temperature, humidity, CO2,
differential pressure, door switches, and many other parameters.
