GRAPHTEC GLT400 is a multi-use data logger that can be used as an 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.

Mount or embed in a system and remote monitoring by PC.

Modbus/TCP for PLC I/O channels. It can be used as additional I/Os.

● Transferring data to PLC via Modbus/TCP protocol
● DC Power only for -20 to +60 operation
● Supports WEB server, FTP server and FTP client network functions for remote monitoring and controlling.
● High Isolation inputs to ensure signals are not corrupted by noise from other channels
● Connect as a remote terminal unit of GL840

Enable to use as PC hosted data logger

Connection to PC via USB ,LAN and Wireless LAN.
Standalone or PC hosted data logger for R&D, Quality and Production

Connect as a remote terminal unit of GL840
