AQ-S214 Alarm and indication IED

AQ-S214 alarm and indication IED can be applied for substation general I/O extension, control and alarm annunciation. Up to six I/O or communication cards 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 AQ-S214 communicates using various protocols including IEC 61850 substation communication standard.
