Check the listing for details. Compact Gateway R-KEY-LT. Listed at 160.00 USD. Compact Gateway R-KEY-LT. ModBUS RTU/ASCII Compact Gateway. Power Supply: 10~40VDC; 19~28VAC. 1x Ethernet Port, 1x serial Port RS232/RS485 commutable. Modbus Bridge Finction: from ModBUS TCP-IP to Modbus RTU/ASCII or from ModBUS RTU/ASCII to Modbus TCP-IP. R-KEY-LT is a compact and reliable Modbus gateway that converts from Modbus TCP-IP protocol to Modbus RTU / ASCII and vice versa. It supports up to 8 TCP-IP Modbus clients simultaneously and 10 Modbus TCP-IP servers. Through this model, serial Modbus slave devices can be integrated into an existing TCP-IP Modbus network as well as Modbus TCP-IP slave devices can be made accessible to serial master. R-KEY-LT can be configured through web server and software tools. The module has Vac / dc power on the same hardware, 1,5 kVac isolation, extended temperature range. The device can be powered also by a 230 Vac power supply unit. Features: Gateway Operating Mode: from ModBus TCP-IP to Modbus RTU / ASCII; from Modbus RTU / ASCII to Modbus TCP-IP.
