Description
Brand: ABB
Product Series: Excitation Systems / UNITROL Control Series
Model: DATX110 (Part Number: 3ASC25H209)
Product Type: I/O Terminal Block / Interface Extension Board

3ASC25H209 DATX110 ABB I/O terminal block
Technical Parameters:
Channel Configuration: High-density interface layout providing multi-channel physical connection points for external field wiring, auxiliary signals, and internal control boards.
Signal Compatibility: Supports a mix of analog and digital I/O signals, including diagnostic feedback lines, measurement inputs, and pulse command distributions.
Galvanic Isolation: Features integrated signal filtering and electrical isolation paths to protect upstream processor cards from field-induced electrical noise or surges.
Interfacing Layout: Equipped with dedicated ribbon cable or high-density pin headers for direct, secure connections to control cards like the DAPC100 or DATX100.
Termination Type: Heavy-duty, vibration-proof screw or spring-clamp terminal blocks ensuring long-term contact reliability under harsh environmental conditions.
Voltage Rating: Designed to handle standard control voltages (typically 24V DC up to 115V/230V AC depending on specific channel configurations).
Mounting Architecture: Rugged PCB design optimized for direct rack or panel mounting within central control cubicles.
Industrial Sectors:
Power Generation Utilities (Hydroelectric, Thermal, Gas, and Nuclear Power Plants), Heavy Chemical and Petrochemical Processing, Metallurgical and Steel Rolling Mills, and Marine Propulsion Engineering.
Application Scenarios:
-
Excitation Cubicle Signal Marshaling: Installed within ABB UNITROL excitation cabinets to act as the primary physical landing point for all field cables (such as sensor feedback, breaker positions, and trip commands) before routing them to the main control processors.
-
Generator Control Wiring Interface: Deployed in utility power plants to bridge external generator instrumentation (like temperature or voltage transducers) with the central automated voltage regulation (AVR) subsystem.
-
High-Vibration Industrial Interfacing: Used on heavy machinery platforms, such as mining hoists or steel mills, where a secure, vibration-resistant terminal interface is required to prevent control loop wire disconnection.
-
Marine Automation Distribution: Utilized inside the main electrical propulsion control panels of large industrial vessels to distribute internal system I/O and isolate critical control paths from the ship’s auxiliary power grids.
