12-bit Voltage Input Adapter

The 12-bit Voltage Input Adapter interfaces with sensors providing 0-5 VDC signals to act as a smart sensor with compatible data loggers. This adapter features both a non-switched input and a battery-saving switched input that extends the life of external batteries. It also provides a trigger signal for controlling power to attached external sensors, while offering digital filtering which improves measurement accuracy with 32 readings/sample.

Environment:
The S-VIA-CM14 Sensor is for use in Indoor and Outdoor environments

Measurements:
The S-VIA-CM14 Sensor supports the following measurements:
DC Voltage

Features :

  • 12-bit resolution
  • Digital filtering improves measurement accuracy with 32 readings/sample—4-20 mA adapter has 60 Hz noise rejection
  • Measurement averaging over logging interval further enhances accuracy
  • Plug-in modular connector for easy interface with HOBO® Weather Station or HOBO® Micro Station data loggers
  • Screw terminal for connecting to sensors
  • Micro Station has room for two adapters and Weather Station has room for ten (adapters mount inside station enclosure)
