How do I use the Vaisala WXT520 with the Model 831?

Model 831 V1.6 supports the Vaisala WXT520 weather transmitter

Next to the legacy models, we now introduce a combined weather sensor, SEN031, with ultrasonic wind sensor.

The picture and features / benefits come straight from the Vaisala brochure.

 

 

The CBL167 cable (20ft) goes from the WXT520 at one end to 3 connectors:

1)    DB9 – WXT520 signal, serial port connects to DVX008A (powered hub is not required and can be connected directly to 831)

2)    831-INT Terminal block plug – WXT520 power (5-32V) connects to 831-INT Auxiliary Power port

3)    DC Power cable socket – WXT520 heater (5-32V) connects to optional PSA027 power supply.  If heater is not wanted to save power it can be left unconnected.

 The 831-INT can’t deliver the 1.1A @ 12V = 13 W, hence the optional PSA027 power supply connection. We suggest configuring the heater only with AC powered systems.

The SEN031 mounts on TRP019 using the TRP008 and on TRP020 using the TRP021.

 

Typical configurations are:

  • AC power permanent: NMS016 + SEN031 + DVX008A + CBL167 + TRP008
  • Battery/Solar power temp:NMS019 + SEN031 + DVX008A + CBL167 + TRP021
  • Component:
    • 831 +  426A12-FF + CBL152 (20ft) signal + CBL154 (20ft) for power
    • SEN031 + DVX008A + CBL167 (20ft)
    • CBL140 --- connects to battery, CBL154, CBL167
