Overview Manuals Specifications Standards Application Scenarios Operating Environment

Features:

  • Strengthens weak control pulses to reliably drive industrial semiconductor devices and actuators.
  • Supports ABB SAMI STAREN transmission equipment and early ABB drive, PLC, and DCS installations used in heavy industries.
  • Operates across 0°C to +50°C with storage capability from -40°C to +70°C and supports 5% to 95% non-condensing relative humidity.
ABB SAFT123PAC serves an important role in industrial automation by providing pulse amplification between the control system and the power stage. The board increases the strength of low-level control signals before they reach high-power semiconductor devices, helping industrial equipment respond accurately to control commands. Signal isolation further contributes to dependable communication within the control architecture.

Industrial facilities operating long-life automation equipment continue to rely on ABB SAFT123PAC for maintaining legacy systems. The board is associated with the ABB SAMI STAREN transmission equipment series and is frequently installed in early SAMI variable frequency drives together with mature PLC and DCS control cabinets. Applications are commonly found in paper mills, steel plants, mining operations, and similar heavy industrial environments where proven control platforms remain in service.

ABB SAFT123PAC combines practical electrical capability with environmental durability. Rated for 6.3 A and 250 V, the board supports continuous operation between 0°C and +50°C while tolerating storage and transportation temperatures from -40°C to +70°C. Relative humidity from 5% to 95% without condensation allows the module to remain suitable for a wide range of industrial operating and storage conditions.

The SAFT123PAC ABB Pulse Amplifier Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
ABB SAFT123PAC pulse amplifier board is an industrial control module developed using ABB technology combined with the earlier Stromberg drive platform. The board is responsible for amplifying weak pulse control signals so they can effectively drive high-power semiconductor devices or industrial actuators. Signal isolation further improves communication reliability between the control system and the power stage.

As a member of the SAMI STAREN transmission equipment series, ABB SAFT123PAC is widely applied in large industrial motor drives and PLC installations. It is commonly found in legacy ABB drive systems, including early SAMI series drives, as well as long-service DCS and PLC control cabinets operating in industries such as paper production, steel manufacturing, and mining. The board contributes to stable signal transmission in demanding industrial environments where dependable control remains essential.

ABB SAFT123PAC features a current rating of 6.3 A and a voltage rating of 250 V. It operates within an ambient temperature range of 0°C to +50°C, while storage and transportation temperatures range from -40°C to +70°C. The board also supports relative humidity levels from 5% to 95% without condensation, making it suitable for industrial installations where environmental conditions may vary during operation and storage.
