24DC Sounder – Reliable notification in your system

The ST22-SD-24DC sounder is a signaling element, ideal for mounting in control and signaling systems. It complements control buttons and indicator lights, increasing safety and informing about changes in the operating status of devices. It will be useful wherever a clear, acoustic notification is needed.

Construction and operating parameters

Made of high-quality materials, the sounder ensures durability and reliable operation. The nickel-plated ring gives it an aesthetic appearance, and the compact dimensions make it easy to install in limited space. Designed for 24V DC power supply, it draws a small current (6 mA), minimizing the load on the power supply. It generates a continuous signal with an intensity of 80 dB, ensuring clear audibility even in environments with increased noise levels. The device is characterized by a carrier frequency in the range of 4…5 kHz and a protection degree of IP30, which means protection against touching and solid objects with a diameter of more than 2.5 mm. To connect the wires, you can use the PS10 terminal block, accepting cross-sections of 2x 1…2.5 mm² for solid wires or 2x 0.75…1.5 mm² for stranded wires.

The ST22-SD-24DC sounder is a solid solution for installers and users looking for a reliable signaling element in control and automation systems. Its versatility makes it applicable in many industrial sectors and in public buildings.
