tGW-722i - Tiny Modbus TCP to RTU/ASCII Gateway with PoE, and 2 RS-232 Ports with Power Isolation (RoHS)
by ICP DAS

ICP DAS USA's tGW-722i module is a Modbus TCP to RTU/ASCII gateway that allows a Modbus/TCP 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 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, which is useful when connecting mainframe computers, servers or other serial devices that use Modbus RTU/ASCII protocols and themselves do not have Ethernet capability. The tGW-722i also adds 3000 VDC isolation and +/-4 kV ESD protection component that diverts the potentially damaging charge away from sensitive circuit to protects the module and equipment from the sudden and momentary electric current.
