General Display & Controller

Product Description

Description

GDC (General Displayer & Controller) series terminal are designed for continuous measurements with Cross Smart Sensors in a general purpose industrial or municipal environment. GDC terminals have the ability to extend network by intelligent sensors with RS485 output, Modbus RTU protocol. GDC terminals supply power to sensors in the meantime of getting signals. A plug and play function can be expected for those sensors in our recommended list, that means if you plug an intelligent sensor into a GDC and it will automatically configure to any of the listed measurements. GDC terminals can be expanded to work with any sensors with analogue or digital outputs for customized configuration.
