24 V DC transformer: Multiple Neosensor powered by a single transformer (correct example)
Multiple Neosensor or a Neosensor and another device in connection can be powered by a single 24 V DC power.
Figure 24. Good wiring example: Two Neosensor (temperature/humidity sensors) powered by a single 24 V DC transformer
Notes for signal wiring
Induction current flowing from Neosensor (humidity sensor, temperature/humidity sensor models) to the controller input circuit
and inadequate time constant of the controller might generate noise. To prevent noise, see the following.
•
Use a controller with low pass filter (40 dB or higher removal ratio in normal mode) that receives signals from Neosensor.
•
For insufficient removal ratio, provide an isolator on the controller input wiring.
Note:
No problem will occur for connecting Neosensor to our controller.
IMPORTANT:
•
When Neosensor is faulty, reduced output may cause over-humidification. Provide safety measure against
over-humidification.
•
Corrosive gas or organic solvent contained in the air may cause sensing error, shorten the service life, or
damage the Neosensor. Before using Neosensor in abnormal atmosphere, consult with our salesperson.
Though common wiring forms a loop, common mode noise affects a little.
