Core Advantages and Technical Highlights

Isolation and signal integrity
With galvanic separation between input and output, DATX100 3ASC25H208 protects control electronics from transients, high common-mode voltages, and ground loop interference. It ensures clean, accurate pulse transmission even in noisy industrial environments.

Multi‑channel flexibility
The board supports up to 16 independent channels, enabling gating, status, and feedback functions across multiple power modules or phases. This flexibility allows designers to consolidate multiple signal paths into one board.

Compact and modular form
Though it provides high channel density and isolation, DATX100 3ASC25H208 is packaged in a format compatible with drive cabinets and modular racks. Its form allows easy replacement or integration with existing drive systems.

High reliability and robustness
Designed for industrial duty, the board tolerates broad temperature ranges and mechanical stresses. Its internal components—transformers, coatings, and insulation—are selected to maintain stability over long-term service.

Diagnostic support and fault containment
When pulses fail to register or if a channel becomes defective, the control logic can detect the anomaly. The board’s robust design helps localize fault channels without compromising other circuits.

Spare and legacy support
Because the DATX100 3ASC25H208 is a standard ABB part in many drive systems, replacements or spares are easier to source. Using this board ensures continuity for legacy drive platforms.

Product Introduction

The ABB DATX100 3ASC25H208 is a high-integrity pulse transformer board specially designed for ABB drive and motion control systems. It functions as a dedicated interface between control logic modules and high-power switching modules by transforming gating pulses while providing galvanic isolation, thus protecting delicate controller electronics from power-side disturbances.

The DATX100 3ASC25H208 accepts low-level logic or gating signals and converts them into isolated driver pulses suitable for thyristor or transistor gating in high-voltage modules. Its design ensures that control logic modules remain electrically isolated from the power stages, which enhances system reliability, fault tolerance, and electromagnetic immunity. Used within ABB’s ASTAT or other drive architectures, this board plays a vital role in bridging the control and power domains securely.
