Sounder 230AC with terminals, nickel-plated ring SP22-SDU-230AC. SP22-SDU-230AC\.

Sounder for control and signaling systems

The SP22-SDU-230AC sounder is a complementary element to control button and signaling light systems, mainly used in acoustic signaling systems. The device is designed to operate with a voltage of 230V AC and is characterized by a volume of 80 dB, providing a clear audible signal.

The sounder's design allows for easy integration with existing installations, and its solid construction guarantees reliable operation.

Construction and technical parameters

The sounder is designed for mounting in standard 22.3 mm diameter holes in control panels and machine enclosures. Connection wires with a cross-section of 1...2.5 mm² (solid core) or 0.75...1.5 mm² (stranded) ensure a safe and stable connection to the electrical installation. The device emits a continuous sound signal with a carrier frequency of 4...5 kHz. The current consumption at 230V AC is 11.5 mA. The IP20 protection degree provides basic protection against touching and ingress of solid objects.
