CL-202-E
Remote CO2/Temperature/Humidity/Dew Point Data Logger Module. Communicable over Modbus RTU, Modbus TCP, MQTT and DCON Protocols. Has Ethernet and RS-485 Ports. Mountable on Ceiling or Walls. Has Relay Output for Indoor Air Quality Control or Alarms. Comes with iAir iOS and Android Phone Apps for Remote Monitoring. (ROHS)
Features
The CL-200 series of data logger devices can be used to record HCHO, TVOC, CO, CO2, temperature, humidity and dew point information, including the date and time stamps, and are able to store up to 450,000 downloadable records.
Real-time data can be accessed from the CL-200 data logger from anywhere and at any time using the free Windows software, the iSO App, or the Android App, as long as they are connected to the same local network as the data logger.
Support is provided for common industrial protocols such as DCON, Modbus RTU, and Modbus TCP, as well as the emerging machineto-machine (M2M)/)IoT (Internet of Things) connectivity protocol – MQTT. The CL-200 data logger can be connected via widely used communication interfaces including RS-485, Ethernet and PoE, meaning that the device can be easily integrated into existing HMI or SCADA systems, ensuring trouble-free maintenance in distributed control systems.

Multi-platform Remote Access Software
Real-time data from the CL-200 data logger can be accessed from anywhere and at any time using the DL300 Utility, the iOS or Android App, or via a regular web browser, as long as they are connected to the same local network as the data logger.

Simple and Powerful DL-300 Utility
The DL-300 Utility is a powerful tool that is designed for configuring the modules, monitoring real-time data, grouping DL-300 and CL-200 modules to view and manage the status of distribution groups, downloading log data, which can be exported to a CSV file that can then be imported into any industry-standard software or spreadsheet for analysis.
