ABB NTU-715 SM9-3055.051.00 Digital Input Termination Module
The ABB NTU-715 (part number SM9-3055.051.00) is a Digital Input Termination Module (DITM) engineered for the ABB Bailey INFI 90 Distributed Control System (DCS). It serves as a field-wiring termination interface, connecting discrete digital signals from switches, sensors, and push buttons to IMDSI or IMDSI02 digital input modules for processing by the central controller.
Signal Termination and Interfacing
The unit provides organized signal routing and electrical termination for binary digital input channels at a nominal 24 V DC voltage level. Designed as a passive board to minimize power load on the backplane, it offers an organized layout that simplifies field wiring and system troubleshooting across control cabinets.
Network Communication and Physical Specifications
Equipped with Ethernet and RS485 communication interfaces, the module features 256 KB of memory to support status logging and system integration. Designed for rack mounting inside system enclosures, it measures 250 mm x 120 mm x 35 mm, weighs 0.82 kg, and operates across a temperature range of -40 to +70 deg C with CE compliance.
