Introduction
The DL-1xxS-WF Series Data Loggers are designed to record temperature, humidity, and dew point values, complete with date and time stamps for each entry. These devices can store up to 650,000 records in downloadable CSV format. Real-time data is accessible anytime, anywhere through a PC utility, Android app, or web interface. The series features two Photo MOS relay outputs that can be triggered based on defined conditions, making them suitable for alarm systems. The DL-101S-WF model includes an LCD display, while the DL-111S-WF is equipped with an illuminance sensor.
All models in the DL-1xxS-WF Series support WLAN connectivity in compliance with IEEE 802.11b/g/n standards and are compatible with Modbus TCP, TCP/IP, and HTML protocols, enabling seamless integration with SCADA systems, HMI interfaces, and other monitoring and control applications.
