AQ-S254 Alarm and indication IED

AQ-S254 alarm and indication IED can be applied to various substation tasks: extending the general I/O, sounding alarms, and control. You can add up to fourteen (14) I/O or communication cards into the device, depending on the requirements pf your application. The logic programming are powerful and easy to use, and it further expands the unit’s application range towards more demanding control, alarm and indication needs. The HMI is large and can be freely programmed, and it provides a quick visualization of the object as well as the status of alarms and events. AQ-S254 communicates using various protocols, including the IEC 61850 substation communication standard.
