The 24 V voltage switches are used for area monitoring. The voltage monitor switches loads off when the voltage signal connected to terminal 15 drops below or exceeds a lower/upper threshold voltage. The standard lower/upper threshold voltages for 12 V applications are 11.5 V/12.5 V and 23.5 V/24.5 V for 24 V applications. Lower/upper threshold voltages can be customized on request.
In addition, combinations with switch-on/switch-off time delay are available. The voltage range monitor switches loads off when the voltage signal connected to terminal 15 drops below or exceeds a lower/upper threshold voltage and switches loads on again when the supply voltage enters the defined threshold voltage range. Please refer to the chapter housing and base plates for additional housing options.
