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).

Logical inputs - solder side of matching male connector

1: + 3.5 VDC

2: Input 1

3: Input 2

4: GND

GND: not used (eventually use for a shield)

+3.5 V

Note: an internal pull-down resistor sets

each input to 0 when the contact is open.

Inputs 4, 5, 6 and 7 - solder side of matching male connector

1: not used

2: power (DC+)

3: GND (docking station) / analog (-)

4: DIO
