I. Basic Information

Model: A58227-001

Manufacturer: MOOG Inc. (Muog)

Type: Digital Buffer Register Logic Board Card

Weight: 0.45 kg

Application fields: MOOG's old servo controllers, hydraulic control systems, aviation/industrial test benches

Current status: The original factory has been out of production for many years, there is no direct replacement model, relying on disassembly/reconditioning/inventory spare parts

II. Function positioning

A58227-001 is a digital interface and buffer logic board in MOOG's early servo/hydraulic control systems. Its core functions are:

Data buffering and locking: High-speed digital signal buffering and register locking between the controller and I/O

Signal matching and driving: Enhance the digital signal driving capability, suitable for long-distance / strong interference environments

Logic timing control: Complete synchronization, handshake, interrupt and other timing logic in coordination with the system clock

Fault isolation: Protect the main control CPU, isolate I/O side interference and faults

Typical applications: MOOG 7000 series, D072, D791 and other old servo valve controllers, hydraulic test benches, aviation engine control units.

III. Technical Specifications (General Parameters)

Power supply: ±15VDC / +5VDC (industrial control standard)

Logic level: TTL/CMOS compatible

Channels: 8/16-bit parallel data buffering (register array)

Operating temperature: 0℃ ~ +55℃ (industrial standard)

Size: Standard Eurocard / rack-mounted board

Interface: Pin sockets / gold fingers, compatible with MOOG's dedicated backplane

IV. Current status and replacement suggestions

Original factory status: Out of production (OBSOLETE), no official technical support, no new production.

Market supply:

New inventory pieces (very few, high price)

Second-hand pieces from disassembly (need testing)

Refurbished pieces (main choice, with warranty)

Alternative solutions:

There is no direct replacement model. Overall upgrade of the controller is required (such as replacing with MOOG G392, D792 series or third-party servo drives)

Maintenance / refurbishment: Professional MOOG repair shops can repair A58227-001 and restore functionality

V. Typical applications

MOOG's old electro-hydraulic servo controllers (such as 728, 761, D072 series)

Industrial hydraulic test benches, material testing machines

Aviation/military engine control, flight simulators

Metallurgy / steel rolling high-precision tension control, position control
