Modbus TCP/IP to Modbus Master/Slave Gateway – 4 Port
PLX31-MBTCP-MBS4
ProSoft Technology’s Modbus® TCP/IP to Modbus® Serial four-port Serial gateway allows high-speed bi-directional data transfers between Modbus® TCP/IP-enabled PACs and Modbus® Serial devices. Modbus® Serial devices are widely used in nearly every industry and include SCADA systems and Power Monitors. Four Serial ports allow for connectivity of up to 400 Modbus® Serial devices, reducing the amount of gateways required for your application.
In addition, the gateway includes several features that allow for simplified integration, reduced commissioning time and optimized performance.
A conformal coating option is available for this product.
