G320A SeriesCommunication Coupler
Features:
★ New automatic addressing method: When a new IO module is connected to the coupler, it can be automatically addressed without manually assign addresses one by one.
★ Support multi communication protocols (such as Modbus RTU/TCP, Profinet, EtherCAT, etc.) and communication methods (Ethernet, RS485, etc.)
★ Free virtual serial port software and dynamic libraries (GSD and HML files).
★ Reduced wiring, easy expansion, strong anti-interference, easy maintenance.
★ Outstanding protection and stability design, with overcurrent, overvoltage, and reverse polarity protection.
★ Firmware upgrades are available via free configuration software.
★ Highly expandable, a single coupler can support up to 16 IO modules.
Technical Parameters

G320A Series Current I/O Module
Features:
★ 8 Channels are independent of each other,and perform signal sampling synchronously.
★ Both software and hardware are combined with filtering processing to achieve fast response and high-precision sampling.
★ 0.5%FS measurement accuracy, can be used with industrial-grade current transformers, and supports independent modification of the measuring range of each channel.
★ Can be used with a coupler to communicate with the host computer, and support multi communication protocols (such as Modbus RTU/TCP, Profinet, EtherCAT, etc.)
★ The default supported transformer range is 50A. Users can adapt different ranges according to actual conditions.
★ After the coupler is matched, the address is automatically obtained without setting the communication address additionally
