The core of the Jastram Analog Control system is the Steering Control
Amplifier (SCA). The SCA processes the signals from the input devices
and directs the
hydraulic power units, the steering gear and, ultimately,
the rudder.
The SCA needs several other components to make up a steering control
system. In order to structure a SCA control system in its most basic form
the following items are needed: Input Device(s), Control Panel(s), a
Command Input Selector (CIS), an electro-hydraulic interface, a Rudder
Feedback Unit (RFU) and in certain cases a Conversion & Change-Over
valve (CCO).
