Occupies fewer nodes, one coupler supports up to 32 slots and 1024 points

XBF4-EC04A
The XBF4 Series I/O modules are designed for use with distributed expandable XBF couplers. The XBF coupler handles fieldbus communication while connecting expanded I/O modules to real-time industrial Ethernet systems through the X-bus Field bus, thus enabling real-time data exchange between expanded I/O modules and the coupler/controller. Featuring comprehensive module varieties and high real-time performance, the XBF4 Series ensures high-speed data acquisition, optimized system configuration, simplified field wiring, and enhanced system reliability for users.
