NWIN002 2xPt100 temperature

The NWIN002 node has connectors for two 4 wire Pt100 sensors and can be battery or battery and DC powered.

• The green connectors for Pt100 4 wire sensors (marked 1 for index 0 and 2 for index 1 sensor) can be disconnected by pulling them upwards away from the circuit board. The sensor wires shall be screwed tight to the connector to minimize the connection resistance. The 2 pairs of wires from two sides of 4 wire PT100 sensor shall be connected to left and right pairs of pins of the sensor connector respectively. If a sensor with 2 or 3 wires is used, then the not used connector pin must be shorted with its pair. It is not recommended to use 2 or 3 wires sensors because the wires resistance will not be compensated which will introduce the measurement error.

• There is a holder for 2 AA batteries.

• A DC jack (5) is used to supply the node from an external 9-12 V power supply.

• There is a send and reset button (4) on the left side of the board. Please make sure that no cables can press this button.

• A transmission LED (3) is in the top left corner of the board. It blinks every time the node sends data to the gateway.

• The blue hinge can be removed for easy routing of cables as described in Enclosure opening.

• The cable slot is used to route the sensor cables as described in Cables routing.
