R-KEY-LT (HW rev. E0)

Modbus <-> IEC 61850 gateway, 1 serial port, 1 Eth port

R-KEY-LT is a compact and robust Modbus gateway that converts from Modbus TCP-IP protocol to Modbus RTU/ASCII and vice versa. It supports up to 8 Modbus TCP-IP clients at the same time, with up to 10 Modbus TCP-IP servers. With this model, serial Modbus slave devices can be integrated into an existing Modbus TCP-IP network, as well as Modbus TCP-IP slave devices can be made accessible to serial masters. R-KEY-LT can be configured via web server and software. It has Vac/dc power supply on the same hardware, insulation 1.5 kVac, extended temperature range. The device can also be powered via 230 Vac power supply unit.
