← Back Jenbacher 222113 Bus Controller EX150

This part is not mounted on the physical engine block, but inside its electronic "brain" (the DIA.NE panel). Its purpose is to act as the "orchestra conductor" for network communications between the various I/O (Input/Output) modules and the central processing unit (CPU). Using the industrial RS485 protocol, this controller transmits and receives high-speed data packets between the engine's sensors (monitoring temperatures, pressures, RPMs, knocking) and the management software.

Essentially, it ensures the engine receives the correct commands without any signal delay. Being a sensitive automation component, it is usually replaced if there is a communication failure on the network bus, a voltage spike in the control cabinet, or during a DIA.NE panel upgrade.
