NTCL01-A Symphony Harmony Network Interface Subsystem TU

NTCL01-A Symphony Harmony Network Interface Subsystem TUProduct Overview The ABB NTCL01 A (also identified as NTCL01A) serves as the primary Communication Link Termination Unit for Symphony Harmony and INFI 90 Distributed Control Systems (DCS). This unit provides the physical wiring interface for high speed INFI Net communication loops, facilitating data exchange between Network Interface Subsystems (NIS) and Network Link Subsystems (NKLS). By managing the connection between local controller nodes and the

and process digital pulse streams from field devices such as flowmeters

The Woodward 9905-463

regardless of the CPU's operational status or the health of the communication bus

While the hardware natively supports dual-redundant pairing on the FCS backplane for high-availability requirements

Status Monitoring: Front-panel LED for Power OK

This module converts digital processor commands into high-fidelity 4–20 mA current signals to drive critical field-side components including fuel valves

and variable speed drives

ready for immediate field installation
