2.3 Logical inputs (on / off)
Several models of docking station allow the HygroLog NT to process up to 2 logical inputs.
Typically this is used to monitor a relay contact, a door contact, etc.
2.4 Pin-out diagrams
Logical Thresholds: logical 1:
≥ 2.8 VDC, logical 0: ≤ 0.7 VDC
2.5 Operating limits
The docking station operating limits are the same as for the HygroLog NT data logger:
HygroLog NT without display:
● -10…50°C with the factory supplied alkaline battery
● -30…70°C with a lithium battery or an external AC adapter
HygroLog NT with display:
● -10…50°C with the factory supplied alkaline battery
● -10…60°C with a lithium battery or an external AC adapter
The HygroClip probes have generally wider operating limits (see individual probe specifications).
