Product Overview

• PN: YYT107A
• Brand: ABB
• Series: Advant OCS / MOD30 old-generation distributed control system
• Type: Rack-mounted main control drive circuit board

• Function: Core signal processing and power drive board inside the ABB Advant system control cabinet. It receives bus instructions from the main controller, processes analog and digital loop signals, outputs drive signals to field execution components, completes closed-loop regulation, logic interlock and equipment fault detection. It communicates with the backplane bus to realize data interaction between the main control unit and field I/O stations, supporting long-term continuous operation of process control loops.
