ALM-CH16 16-Channel Fault Annunciator

Information

ALM-CH16 is a high-integration fault annunciator equipped with 16 independent signal input channels, specially developed for centralized fault signal collection on electrical control cabinets. Adopting standard 96×96mm panel mounting structure and stable MCU control core, this compact annunciator supports passive dry contact input with built-in 15V DC power supply for each channel, requiring no extra power from external sensors. Each channel corresponds to a high-brightness red LED indicator with replaceable custom label strips, enabling operators to rapidly locate fault sources at a glance. It features three physical buttons (MUTE, TEST, RESET) on the front panel for manual alarm control, and wide universal power input of 85–265V AC/DC to adapt diverse power distribution environments. This 16-channel fault annunciator realizes multi-mode alarm logic: once any channel detects a fault signal, the matched LED flashes continuously at over 1Hz frequency, the built-in buzzer triggers acoustic alert, and the collective alarm relay closes synchronously. After manual reset, the indicator stays steady on if the fault persists, and turns off only after the fault clears. Besides centralized alarm output, it provides independent self-fault relay contacts to report device power failure or internal circuit breakdown. Equipped with isolated RS485 Modbus-RTU communication interface, it uploads real-time 16-channel fault status to SCADA, EMS and centralized monitoring platforms. All relay outputs adopt passive dry contacts with 5A@250VAC load capacity, compatible with external buzzers, warning lights and interlock circuits.
