Description
BUS-3 solenoid control unit
BUS-3 is an aircraft solenoid control unit used in onboard automatic control, navigation and flight-control complexes. In the supplied context, the unit is associated with systems such as ABSU-134 and IK-VK-80. The block provides switching and control of solenoids used in aircraft actuating circuits. It receives commands from automatic control equipment and sends control or power signals to electromagnetic actuators, valves or related components.
Function of BUS-3 in aircraft systems
The main function of BUS-3 is control of aircraft solenoids and electromechanical components. The unit switches control signals and issues power pulses to solenoid coils used in hydraulic, pneumatic or other aircraft control circuits. This allows automatic control systems to actuate valves or mechanism control elements through electromagnetic commands. BUS-3 works as an interface between the automatic control computer / control logic and the physical solenoid-driven elements of the aircraft system.
Integration with ABSU and navigation complexes
In the supplied context, BUS-3 is connected with flight-navigation complexes and automatic control systems, including ABSU-134 for Tu-134 aircraft and IK-VK-80 navigation complexes. In such systems, the block is structurally and electrically linked with actuating mechanisms and control channels. It receives signals from control computers or automatic-control units and transfers them to solenoids that switch hydraulic or pneumatic circuits of servo drives or related mechanisms. Applicability depends on the specific aircraft and system configuration.
Built-in monitoring and safe operation
BUS-3 is described as having continuous built-in monitoring. This monitoring checks the condition of internal circuits and solenoid control lines during operation. If a fault is detected inside the unit or in a solenoid circuit, the block can remove the “serviceable / ready” signal from the common system bus. According to the source context, this results in safe disconnection of the automatic control mode and transfer to manual piloting. Exact monitoring logic and fault thresholds must be verified by the relevant system documentation.
Installation and construction of BUS-3
The BUS-3 unit is installed in avionics or instrument equipment compartments of the aircraft. In the Tu-134 context, blocks of the ABSU system are located in technical compartments near the cockpit area and mounted on common shock-mounted racks or frames. BUS-3 is described as a quick-removable cassette-type aviation block with a rear knife-type connector for installation into an amortized frame. This construction supports fast replacement, bench testing and maintenance access.
Identification and ordering of BUS-3
Before ordering BUS-3, the buyer should confirm the aircraft type, parent system, required modification, condition category and documentation set. It is important to clarify whether the unit is required for ABSU-134, IK-VK-80 or another aircraft automatic control system. The block may be needed for repair of automatic control equipment, troubleshooting of solenoid control circuits, replacement of a defective unit or spare parts stock. Product passport, acceptance marks, wiring documentation and bench-test records should be agreed before shipment.
