The 12-bit 4-20 mA Input Adapter interfaces with any sensor providing a 4-20 mA signal to connect to smart sensor 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 and 60 Hz noise rejection.
Features:
- 12-bit resolution
- Digital filtering improves measurement accuracy with 32 readings/sample4-20 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
- Measurement range: 4-20 mA (measures down to 0 mA to detect error condition)
- Operating Temperature Range: -40 to 75 C (-40 to 167 F)
- Accuracy: +/- 40 uA +/- 0.3% of reading (over operating temperature range)
- Resolution: +/- 4.93 uA
- Input impedance: 124 ohms (differential input)
- Sensor Trigger Source: Voltage: 2.5 V +/- 2.4%; maximum current: 1 mA
- Trigger Timing:
- Warm-up Time: 300 ms +/- 3% (fixed)
- Measurement Time: 16.6 ms +/- 3% to filter out 60 Hz noise
- Cable Length: 14 cm (5.5 inch)
