The DL-100-E/DL-101-E series of Data Logger devices can be used to record temperature, humidity and dew point information, including the date and time stamps for each record, with up to 600,000 downloadable records able to be stored. Real-time data can be accessed from the DL-100-E/DL-101-E Data Logger from anywhere and at any time using the free Windows software, the iOS App, or the Android App, as long as it is connected to the same local network as the Data Logger. The DL-100-E/DL-101-E Data Logger supports popular industrial protocols such as Modbus TCP, as well as the emerging machine-to-machine (M2M)/IoT (Internet of Things) connectivity protocol – MQTT. The DL-100-E/DL-101-E Data Logger can be connected using a range of communication interfaces including Ethernet and PoE, meaning that the device can be easily integrated into existing HMI or SCADA systems, ensuring easy maintenance in a distributed control system.
