Instruction Manual – NPS914 Alarm and Indication IED
2. General
The NPS914 alarm and indication relay is a member of the NP900 product line. The hardware and software
are modular: the hardware modules are assembled and configured according to the application's I/O
requirements and the software determines the available functions. This manual describes the specific
application of the NPS914 alarm and indication relay. For other NP900 series products please consult their
respective device manuals.
NPS914 may be applied as a substation alarm sounder, a substation general I/O extension unit or in any
other application that requires extended I/O capabilities. The local indications are visualized conveniently
through the freely programmable alarm LED display and event list. Up to six (6) optional I/ O or
communication cards are available for extensive monitoring and control applications. NPS914 can be
connected to a substation automation system by using various standard communication protocols,
including the IEC 61850 substation communication standard.
