GT72R Touchscreen Paperless Recorder
This product is an industrial paperless data logger with a 7-inch color touchscreen display and up to 32 channels of isolated universal signal input. It can accept industrial standard signals such as current, voltage, thermocouples, RTDs, and frequency (customizable). It can also be configured with alarm relay output and current transmitter output. It acquires signals in real time, saves channel data to form historical data, and records at intervals as fast as 1 second. Historical data can be quickly transferred via USB devices. It supports RS485 and Ethernet communication interfaces. Data and status are displayed in various formats including numerical values, bar graphs, and curves.
