VSC100 Sampler Controller
Simplifies Controlling the Sampler
weather applications water applications energy applications gas flux and turbulence applications infrastructure applications soil applications


The VSC100 is included with the PVS5120-series water samplers, and it can be ordered as a replacement part.

The VSC100 allows a sampler to be controlled by an external data logger or PLC device without the need to independently program the sampler. The VSC100 is used instead of a controller with a keyboard display. For most deployments, pushing a button after the sampler is in place is all that needs to be done to set all of the time settings (purge time, etc.).

Benefits and Features

  • Trigger sample collection from the PLC via:
    • Modbus or PakBus over RS-485
    • Pulse input: switch closure or waveform
    • SDI-12
    • Time based (no data logger needed)
  • Get detailed return feedback regarding sample via:
    • Modbus or PakBus over RS-485
    • SDI-12
    • Pulse (only returns sample completion)
  • USB connection to PC for configuration via our Device Configuration Utility (DevConfig)
