ALM-CH30 30-Channel Alarm Annunciator

Information

ALM-CH30 is a high-density alarm annunciator equipped with 30 independent signal input channels, specially engineered for large-scale energy and industrial automation control panels. Adopting 144×144mm standard panel mounting form factor, this alarm annunciator integrates optically isolated input circuits with built-in noise suppression filters, which effectively eliminate electromagnetic interference and guarantee stable signal acquisition under harsh high-noise industrial environments. Each of the 30 channels matches an ultra-high brightness red LED indicator with replaceable custom label strips, allowing operators to quickly pinpoint fault locations at a glance. It supports universal wide power input of 85–265V AC/DC and optional 24VDC supply, covering most power distribution system specifications. This 30-channel alarm annunciator realizes complete visual and audible alarm logic. Once any fault dry contact signal is triggered, the corresponding LED flashes continuously above 1Hz, while the internal buzzer sounds and the centralized alarm relay closes simultaneously. Three physical buttons (MUTE, TEST, RESET) on the front panel support one-click silence, full lamp test and alarm acknowledge: after reset, the LED stays steady on if the fault persists, and turns off only after the abnormality is cleared. It is fitted with three groups of passive relay outputs for separate collective alarm, external buzzer drive and self-fault warning. If the annunciator loses power or suffers internal circuit breakdown, the self-fault contact sends out a failure signal automatically. In addition, an isolated RS485 Modbus-RTU communication port enables real-time upload of all 30-channel alarm status to SCADA, EMS and central monitoring platforms for remote supervision.
