ABB SNAT-22 SNATZ 22 AVPA 009 Stromberg Control Board

Description

The ABB SNAT-22 SNATZ 22 AVPA 009 is a legacy control board used in ABB Stromberg drive systems.

The PCB is physically marked ABB STROMBERG DRIVES and SNATZ 22 AVPA 009. A socketed memory or program device on the board carries the identification SNAT-22 SCI 00B / 900314 RVKY.

The assembly combines logic processing, analog signal-conditioning components, terminal connections, and a multi-pin backplane connector. These features indicate a dedicated drive-control interface role within the original ABB Stromberg system architecture.

Because SNAT-22 is legacy hardware, replacement should be based on the complete board markings and installed system configuration. The SNATZ 22, AVPA 009, and SCI revision markings should be checked before substitution.

Technical Specifications

Board Identification

These identifiers are visible directly on the supplied hardware and are more useful for exact replacement than the generic description “control board.”

Hardware Characteristics

The board contains a mixture of digital logic ICs, analog signal-conditioning components, discrete transistors, resistors, capacitors, and magnetic components.

A Siemens SAB 8031A-P microcontroller is visible on the PCB, together with additional logic devices and a socketed program memory device.

The design uses a large multi-pin system connector along one edge and a separate screw terminal block for external connections.

These details are specific to the photographed SNATZ 22 AVPA 009 assembly.

System Association

ABB legacy engineering documentation references SNAT 22 within Stromberg drive wiring and terminal diagrams. This supports its role as a dedicated board within an ABB drive control system rather than a standalone controller.

Installation & Commissioning

• Verify the SNATZ 22 marking before replacing the installed board.
• Confirm the AVPA 009 board variant.
• Record the SCI 00B / 900314 RVKY program identification.
• Photograph all terminal and backplane connections before removal.
• Isolate the drive before handling the PCB.
• Use ESD precautions when handling the board.
• Inspect connector contacts and terminal wiring before installation.
• Confirm the replacement board uses the same hardware and program configuration.
• Verify drive control functions after installation.

Replacement Notes

• Do not source the board only by the generic name SNAT-22 Control Board.
• Match SNATZ 22, AVPA 009, and the program identification where possible.
• A visually similar SNAT board may use different firmware or system configuration.
• Preserve the original programmable device or configuration information during repair work.
