1. Brief Description 

The NDA 100/3-2 TH(S) series systems are electronic devices designed to monitor air temperature and 
relative humidity. The measurements are made by a high-precision digital sensor, which can be internal 
plug-in type (version THS) or external wired (version TH). Measured values are displayed on a large size LED 
display, or can also be viewed remotely on a PC and logged in a database for later review. For this purpose 
various communication interfaces are offered: USB, RS485, LAN or PoE LAN and DataLoggerTH software 
application is available for download. In case of LAN interface, user can monitor the measured temperature 
and humidity on the local Intranet as well, assuming his PC is located on the same LAN network.

Communication of display with external sensor or with external devices (e.g. PCs or PLCs) is performed via 
MODBUS protocol. Displays equipped with USB or RS485 interface use MODBUS RTU protocol, whereas 
displays with Ethernet LAN interface use MODBUS TCP/IP protocol. This protocol can be used to obtain 
temperature and humidity data from display and to adjust display’s configuration settings using external 
devices such as PCs, PLCs and various control units. Display can therefore be easily integrated into various 
data acquisition systems or building management systems - BMS.

2. Models Available

There are eight different display and four sensor types available. Their selection depends on intended 
application. Some applications require displaying temperature and humidity values without a need of 
logging measured values. Other may require remote connection to a PC and data logging.
