Sonaler SC110NJ NSNBC01 Industrial Relay Module

SC110NJ is a panel‑mount piezo buzzer from Mallory Sonalert Products, engineered for in‑panel audible alerts in industrial equipment. This active, internally driven buzzer includes its own drive electronics and accepts a wide supply range from 30 to 120 V AC or DC, drawing about 24 mA. The round body measures 42.85 mm in diameter and is designed for panel mounting with a 0.250" (6.35 mm) screw‑terminal connection for straightforward wiring. Sound output is specified at about 80 dB when driven at 30 V, with a nominal operating frequency near 2.9 kHz (datasheets also note a typical 2.4–3.4 kHz range for Mallory Sonalert buzzers). Typical applications include audible indicators on control panels, alarm or alert signaling in industrial gear, and other scenarios where a compact, reliable alert device is needed. The SC110NJ line is cataloged by Mallory Sonalert Products Inc. and appears across multiple alarm/buzzer inventories and distributors, reflecting its role as a dedicated audible notification component in machinery and automation systems.
