MB Series Plastic with LED 24V AC/DC 22 mm Buzzer
The MBZS024S pairs a 90dB audible alert with a visual LED cue in one compact 22mm unit, so operators can't miss a fault or process alarm even in a noisy plant. At just 20mA, it drives directly from a PLC output with no extra hardware.

Frequently Asked Questions
Can I drive this directly from a PLC output?
Yes — at 24V AC/DC and just 20mA draw, it's compatible with most PLC digital outputs without needing an interposing relay.
Is 90dB loud enough to hear over factory floor noise?
90dB is comparable to a passing truck or industrial machinery — generally audible over typical factory background noise from several metres away, though very loud environments may need a supplementary visual-only strobe instead.
Is this suitable for washdown or outdoor mounting?
It's IP50 rated (dust-protected, not water-jet rated), so it's best suited to indoor control panels rather than washdown or outdoor environments. For a washdown-rated buzzer, check the MBZX024SE (IP65) instead.
What's the difference between this and the 230V version?
This is the low-voltage variant, suited to PLC/relay-driven circuits. If your panel runs mains-voltage alarm circuits directly, use the MBZS220S (230V AC) version instead.
Industry Applications
- BMS & control panels — combined audible/visual fault or alarm annunciation
- Process equipment — end-of-cycle or fault signalling on PLC-controlled machinery
- Manufacturing control stations — alerting operators to a stop, fault, or attention-required condition
