LED/buzzer combination 450 with acknowledgement function
Unique acknowledgement function
The LED/Buzzer Combination 450 with acknowledgement function from WERMA sets new standards for optical-acoustic signalling. The combination unites a very bright light signal with the powerful sound of a buzzer. This product also features a unique acknowledgement func-tion: by gently pressing the front surface of the product the audible signal can be turned off in a matter of seconds. The acknowledge-ment signal is sent to the control unit over an electronic switch and the malfunction is only indicated by the optical signal.
Frontal and side light illumination and a sound output of 80 dB
The LEDs radiate light both frontally and to the side, thus ensuring op-timal all-round signal visibility. The 3 KHz continuous tone at a sound output level of 80 dB can be clearly heard above environmental noise.
Long life and maintenance free
Despite the range of features the LED/Buzzer Combination is highly economical and requires just 40 to 80 mA. As a result of the durable and maintenance free LEDs the combination has a life duration of up to 50,000 hours and can be simply connected using screwable con-nectors.
The fact that the device does not need a sound outlet, enables it to conform to the high protection rating IP 65. The combination is there-fore resistant to dust and splashed water. It is especially suitable for the control panel and switch gear programme due to its compact size. The 24 V model can be directly controlled by any PLC.
