ALM-CH16 fault annunciator are installed on the cabinet panel. They are simple, compact and can improve wiring efficiency. They are universal alarms suitable for power control and monitoring systems. The alarm uses a highly reliable MCU to monitor external status in real time. When an abnormality occurs, the corresponding indicator light on the panel lights up, the buzzer sounds an alarm, and the alarm relay responds quickly.
The alarm can be muted, reset, tested, etc. by pressing buttons. The product supports optional RS-485 digital interface communication (using MODBUS-RTU communication protocol).
