AQ-S254 Alarm and indication device
The AQ-S254 alarm and indication device 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 of your application. The logic programming is powerful and easy to use. It also further expands the device’s application range towards more demanding control, alarm and indication needs. The HMI is large and can be freely programmed, and provides a quick visualization of the object as well as the status of alarms and events.
