More accurate data with digital filtering

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.

The 12-Bit 0-5 Volt Input Adapter is used for measuring voltage levels and provides a trigger source voltage for powering external sensors and an open collector trigger. The input adapter has a plug-in modular connector that allows it to be added easily to a logger.

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
• Screw terminal for connecting to sensors
• HOBO RX3000 and U30 stations have room for two adapters
• Use with HOBO USB Micro Station and HOBO MicroRX Station requires Smart Sensor Consolidator Box (S-ADAPT-6) and an extension cable
• Represents one data input channel

Outdoor use requires sensor to be within a weatherproof enclosure.
