Disadvantages of passive relay protection devices
The disadvantages of solid-state relays are their high cost, sensitivity to temperature and voltage fluctuations, and need for external power sources. Complexity: Requires more sophisticated design and. Today, power disruptions such as blackouts can have a domino effect – a series of disruptions. Passive disabling devices (like ignition kill switches or immobilizers) are basic anti-theft tools, but they only act after a break-in. Modern theft methods like relay attacks and CAN Bus hacks bypass them easily. Businesses relying solely on passive systems risk major losses and weak insurance. Relays also do have some disadvantages along with the many advantages that they can offer. With any movin...
