Yokogawa S9883FA CPU Backup Battery Single Board A: It connects Advant Controllers

A: It connects Advant Controllers (410/450) with AC 800M controllers using the MB300 protocol

This makes it essential for applications where consistent and stable power management is critical

responsible for converting binary (on/off) control signals from the controller into electrical signals that drive field devices

whereas older FCM100 versions use slower Nodebus or 10 Mbps Ethernet interfaces
