The NDA 100/3-2 TH RG L20 230AC LAN is an electronic monitoring device which displays air temperature and humidity on a large format. It is suitable for use in indoor environment (public institutions, banks, bus and railway stations, airports, schools, offices, hotels, restaurants, etc.).

Its enclosure consists of aesthetic anodized aluminum frame, non-glare front cover glass and steel back panel. Excellent readability is ensured by super-bright 7-segment LED modules with a wide viewing angle.

External temperature and humidity sensor connects to display with cable via serial RS485 inerface.

Display is equiped with Ethernet TCP/IP interface for connecting to LAN network and data logging of measured values. Power supply cable is attached from the back side.

Application Diagrams

The following are some possible applications of large size temperature / humidity displays with internal or external temperature and humidity sensors.
Depending on communication interface, these devices can be used as stand-alone or in a RS485, LAN, or LAN PoE network system.
