Overview
The ABB NTHS03 Termination Unit serves as an essential interface between hydraulic servo modules (like IMHSS03, SPHSS03/04/05/13) and field devices such as valves, I/H converters, or LVDTs. It routes signals, provides power, and supports protection features to ensure consistent operation under demanding control scenarios.
Engineers select the NTHS03 because it features reliable fuse protection, configurable dip-shunts and jumpers, and compatibility with both internal Infi-90 backplane power and external sources. Its compact form factors ease mounting on the NFTP01 Field Termination Panel within standard ABB Harmony racks.
