ICP Electronics Australia Introduces ICP DAS Modbus / TCP to RTU / ASCII tGW-725i Gateway with PoE and 2 Isolated RS-485 Ports


ICP Australia is proud to present the tGW-725i from ICP DAS, which is a Modbus TCP to RTU / ASCII gateway that allows a Modbus / TCP host to communicate with Modbus RTU / ASCII serial devices through an Ethernet network and eliminates the cable length limitation of legacy serial communications devices.

The module can be used to create a paired connection application (as well as a serial bridge or serial tunnel application), and then can route data over TCP / IP between two Modbus RTU / ASCII serial devices, which is useful when connecting the mainframe computers, servers or other serial devices that use Modbus RTU / ASCII protocols and themselves do not have Ethernet capability.

The tGW-725i also adds 2500 VDC isolation and a +/- 4 kV ESD protection component which diverts the potentially damaging load from the sensitive circuit to protect the module and equipment from sudden and momentary electrical current. In addition, the tGW-700 module has a powerful 32-bit MCU to enable efficient management of network traffic and also has a built-in web server that provides an intuitive web-based management interface that allows users to change the configuration of the network. module, including static DHCP / IP, gateway / mask settings, and serial port settings.
