A new EtherTrak redundant Ethernet I/O gateway provides a redundant Ethernet interface for distributed I/O clusters.
A new EtherTrak redundant Ethernet I/O gateway provides a redundant Ethernet interface for distributed I/O clusters.
The ET-GT-ST-3 extends Sixnet's rugged EtherTrak automation line of real-time industrial Ethernet switches, direct Ethernet I/O, and Ethernet to Modbus converters.
Without redundant networking, simple cable failures can lead to loss of control and I/O data.
Using the ET-GT-ST-3 helps ensure fault-tolerant I/O updates in mission critical systems.
Because the ET-GT-ST-3 has two Ethernet ports, two unique IP addresses can be used for redundant networking purposes (the secondary IP provides the backup communications path).
Open Modbus/TCP, ASCII, and RTU (including master, slave and pass-through functionality) are supported by the ET-GT-ST-3.
The ET-GT-ST-3 can interface with thousands of I/Os.
There is tremendous flexibility in system design with the ET-GT-ST-3 because there are more than 20 types of SixTrak I/O modules to connect with.
The ET-GT-ST-3 can also poll EtherTrak Ethernet I/O modules.
No programming is required to setup the ET-GT-ST-3 because Sixnet's setup 'wizards' provide quick and easy configuration.
The ET-GT-ST-3 can be DIN rail or direct panel mounted, and comes encased in a rugged metal shell for added durability.
The ET-GT-ST-3 can withstand temperature extremes from -40 to +70C and is Zone 2, UL, CSA, CE and DNV rated.
