Monitorless Data Logger GLT400

Multi-use & Multi-function Input Data Logger

GLT400 is a multi-use data logger that can be used as a extension unit and a stand-alone measurement such as utilization at research and development, newly expanding the sector to production engineering and production, incorporation into control panels and devices, data acquisition from PLCs via Modbus/TCP, and as PC loggers.
Three types of analog input terminals are available in the lineup, which can be selected due to the input type, and can be expanded from the standard 20 channels to a maximum of 200 channels.
We can provide a document on how to connect to PLCs and other devices using Modbus/TCP.
