S-VIA-CM14 HOBO 0 - 5 Vdc Adaptor for External Sensors

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.

• 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)
• Represents one data input channel
