Description

The DNS-14 is an intelligent room sensor with a 3-digit, seven segment, LCD display, capable of displaying a wide-range of digital or analog values, including setpoints, temperature, air flow, heating and cooling status, fan speed, valve and damper position, and more.

The DNS-14 communicates on Delta’s LINKnet network or directly on a BACnet MS/TP network. When connected to a Delta Controller, on a LINKnet network, the DNS-14 provides programmable remote sensor capabilities. When connected on the BACnet MS/TP network, it functions as an independent BACnet sensor device.

Application

For use in diverse applications that require one or

more low cost, programmable sensors.
