BPS1-1A
SPUT-4-1 Sum-Conversion Unit
Description
BPS1-1A sum-conversion unit
BPS1-1A is an aircraft electronic unit identified in Russian aviation inventories as a “sum-conversion block.” It is listed together with BI16-1 and BI16-2 in the SPUT-4-1 fuel-system equipment family. The correct part designation is BPS1-1A; SPUT-4-1 describes the associated programmed fuel-management and measuring system and should not be merged into the Part Number.

BPS1-1A and SPUT-4-1 application
SPUT-4-1 is documented on the Ilyushin Il-76 as a system supporting fuel quantity measurement, programmed fuel control and related indication and command functions. The BPS1-1A designation indicates conversion of a summed system quantity, but the exact input circuits, scale and output format require the product passport. The card therefore records the confirmed system relationship without inventing an electrical specification.
Related measurement blocks
BPS1-1A is associated in the same equipment listings with the BI16-1 and BI16-2 measurement units. These products perform different functions and are not alternatives to one another. Selection must follow the SPUT-4-1 functional diagram, full designation, connector arrangement, calibrated execution and installed aircraft configuration.
BPS1-1A technical-data limits
The reviewed sources do not provide a dependable standalone supply voltage, pinout, conversion law, signal levels, accuracy, mass or dimensions for BPS1-1A. Such values must be verified from the BPS1-1A passport and the approved SPUT-4-1 maintenance documentation. Parameters of BPS1-1, other BPS units or another aircraft fuel system must not be applied to the “1A” execution by analogy.
Inspection and ordering BPS1-1A
Incoming inspection should confirm every nameplate line, the 1A suffix, connectors, keying, contacts, housing, mounting points and seals. Bench testing requires the correct input simulation and specified load for the SPUT-4-1 circuit. An enquiry should state BPS1-1A, aircraft and system execution, quantity and required passport or test documentation. More related equipment is listed under Electronic Control Units.
