R-KEY-LT

R-KEY-LT

DIN-rail RS485 to Ethernet converter (multi-slave TCP)

The R-KEY-LT is a communication gateway from SENECA Automation Interface. It enables communication between products communicating via Ethernet or serial port .
In CRE TECHNOLOGY applications, we use its communication capability for the Modbus protocol to switch from Modbus TCP/IP to Modbus RTU (via RS485 COM port ) and vice versa. The big advantage of this gateway is that it can link an RTU Master product with several TCP/IP Slaves, which the reference USR-DR302.
This gateway enables fast, efficient commissioning of your various projects. It can be configured using the manufacturer's software, which can be downloaded here.
