ICP DAS GW-2200i Modbus TCP/UDP to RTU/ASCII gateway

Click2Contact

ICP DAS’s GW-2200i module is a Modbus TCP/UDP to RTU/ASCII gateway that enables a Modbus TCP/UDP host to communicate with serial Modbus RTU/ASCII devices through an Ethernet network and eliminates the cable length limitation of legacy serial communication devices.

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

With multiple isolated RS-232/485/422 ports and two Ethernet ports, the device allows daisy chain connection, which enables flexibility in locating devices and easy installation. The product also adds 3000 VDC isolation and ±4 kV ESD protection component that diverts the potentially damaging charge away from a sensitive circuit to protect the module and equipment from the sudden and momentary electric current.
