NP   S914

Alarm and indication IED with IEC 61850 protocol

The optimal management of electrical power systems is based in particular on the reliability, availability and communication skills of protection, measurement and automation devices.
The NPS914 alarm and indication IED can be applied for substation general I/O extension, control and alarm annunciation. Optional cards (I/O, communication...) can be inserted depending on application requirements. Easy to use and powerful logic programming expands further the application range to more demanding control, alarm and indication needs. Large freely programmable HMI display provides quick visualization of the object, alarm and event status.
The NPS914 communicates using various protocols including IEC 61850 substation communication standard.
