PROSOFT 5301-MBP-DFCM Standalone Modbus Plus

Product Description

5301-MBP-DFCM is DIN rail aluminum shell protocol converter for hybrid automation systems. It realizes transparent bidirectional data exchange between Modbus Plus token ring network 

and Rockwell DF1 serial equipment, each port supports independent master/slave mode. Equipped with 1 DB9 Modbus Plus port and 4 configurable RS232/422/485 DF1 serial channels, 

built-in large data mapping buffer, no PLC program modification required. Widely used for integrating legacy Modicon PLC and AB SLC/MicroLogix systems, core spare for old 

mixed-brand control cabinet maintenance.
