The DNL920A is a wireless logger featuring internal temperature and humidity sensors and four external 2-wire inputs each capable of measuring temperature, voltage, current, frequency, pulse as well as dry contact.
With high accuracy and resolution across all inputs, the DNL920A records all measured data to its internal memory before transmitting wirelessly over the DataNet network to the online DataSuite monitoring software.
The DNL920A’s compact and robust casing is suitable for most industrial applications. This model includes a 2-row LCD screen and two-button keypad for standalone operation, such as joining the device to the wireless network, as well as a rechargeable battery pack for long-term deployment. Depending on the logger configuration, the DNL920A can run up to several months on one charge. External alarm output is available as well as 12 V excitation for powering external sensors.
The DNL920A can also function as a Repeater, providing the logger with the ability to not only record and transmit its own data but also to relay transmissions from other units, thereby enhancing the DataNet’s mesh network capabilities.
