ABB Bailey INIIT12 Transfer Module | No Battery, DB-25 & 36-Pin

The ABB Bailey INIIT12 Transfer Module ensures reliable signal routing for critical control systems. This module manages analog input transfers with minimal signal degradation. It weighs approximately 0.45 kilograms and fits standard Bailey racks. Its compact dimensions measure 25.4 cm in length, 12.7 cm in width, and 3.2 cm in height.

Key Technical Parameters

The INIIT12 includes one front-facing DB-25 female connector for field wiring. Additionally, it offers one terminal block with 36 discrete connection points. The module uses dual backplane interfaces for redundant communication paths. It does not contain onboard batteries or large capacitors. Therefore, the unit requires no periodic energy storage replacement.
