The user must read the product documentation before proceeding with the information provided in this section.
The NEON Temperature Transmitter requires two main pieces: the transmitter and the temperature probe. The temperature probe can be an industrial thermocouple or an RTD PT-100 which can be purchased through a 3rd party or in some cases with TWTG.
The NEON transmitter must be mounted using the pre-mounted bracket, which must be earthed. On a flat surface, you can use the mounting holes. Slots and screw holes are designed for M4 fasteners while the threaded hole uses a M5 bolt.
An example of a mounted NEON transmitter using the mounting holes is presented next.
You can mount the NEON transmitter to a pole using a 14 mm wide band clamp. Please note that in this case the bracket must be earthed as well.
Follow the next instructions to connect the thermocouple to the NEON Temperature Transmitter interface. Please refer to the product documentation to complement the information provided in this section.
Strip the wires down by 7mm.
Insert the cable through the waterproofing O-Ring and cable gland nut.
Open the locking lever of the push-in connector.
Press the thermocouple wire in the connector, and use the above table to verify polarity. Do not use excessive force. Ensure the correct polarity, as the device will not function properly with reversed polarity.
Close the locking lever of the push-in connector.
Tighten the nut with the O-Ring.
The thermocouple to be used alongside the NEON Temperature Transmitter can be type: K, J, T, N, E, B, R, or S. By default, the NEON Temperature Transmitter is configured to use a type K thermocouple. If the user wants to change the sensor type being used, they must generate a downlink and change the configuration of the device. Please refer to the configuration section for more information.
The thermocouple wire must be connected to the temperature interface as illustrated in the following image:
The pinout of the interface when using a thermocouple is the following one:
Pin 1
Not used
Pin 2
Thermocouple Positive Connection (+)
Pin 3
Thermocouple Negative Connection (-)
Pin 4
Not used
The NEON temperature transmitter can be used alongside a 3-wire RTD. By default, the NEON Temperature Transmitter is configured to use a type K thermocouple. To use the RTD the user must generate a downlink and change the configuration of the device. Please refer to the configuration section for more information.
If your NEON Temperature Transmitter is from batch AA and product type DS-TT-01-xx the pinout for the RTD wire deviates from this guide. Please refer to the product manual of the device for the correct information.
The RTD wire must be connected to the temperature interface as illustrated in the following image:
The pinout of the interface when using an RTD is the following one:
Pin 1
RTD sense (red)
Pin 2
RTD + (red)
Pin 3
RTD - (white)
Pin 4
Not used
The NEON temperature transmitter can be used alongside a 2-wire RTD. By default, the NEON Temperature Transmitter is configured to use a type K thermocouple. To use the RTD the user must generate a downlink and change the configuration of the device. Please refer to the configuration section for more information.
The RTD wire must be connected to the temperature interface as illustrated in the following image:
The pinout of the interface when using an RTD is the following one:
Pin 1
RTD + (red)
Pin 2
Not used
Pin 3
RTD - (white)
Pin 4
Not used
The installation of the external temperature element is dependent on the use case and the element being used. Please refer to your provider's documentation to learn how to install it properly.
