ALM-CH16 16 Channels Fault Annunciator Relay
- Product Details
- Company Profile
The ALM-CH16 16-channel fault annunciator is installed on the electrical cabinet panel. It is simple, and compact, and enhances wiring efficiency. These universal alarms are suitable for power control and monitoring systems. The alarm utilizes a highly reliable MCU to monitor external status in real time. When an abnormality occurs, the corresponding indicator light on the panel illuminates, the buzzer sounds an alarm, and the alarm relay responds promptly.
The alarm annunciator can be muted, reset, tested, etc., by pressing buttons. The product supports RS-485 digital interface communication (utilizing the MODBUS-RTU communication protocol).
