Technical description
Alarm and communication card intended as an option for ECO series products with CEO-FLX motherboards. The card is used to transmit alarm, status and monitoring information between the ECO device and external systems. It is equipped with two relay outputs (NO/NC/COM). One relay signals a power outage, and the other acts as a buzzer alarm (fuse failure as factory default). Both relay outputs can be set and customized via PowerWatch depending on your needs. The card is fully compatible with PowerWatch. Installing the board enables configuration and monitoring from the ECO unit to the PowerWatch, providing extended functionality for operational control and event management. The alarm and communication board is mounted directly on the CEO-FLX board. It is intended for installations where flexible
