Battery voltage monitoring to prevent accidental switching: Some battery separators (also called voltage controlled relays or cut-off relays) disconnect a battery in case of short but high amperage. Sometimes a battery separator will not connect a large but uncharged battery bank either, because the DC voltage immediately drops below the disconnect value once the batteries are connected. The software of the Cyrix-ct 12/24 does more than just connect and disconnect on the basis of battery voltage and a fixed time delay. The Cyrix-ct 12/24 looks at the general trend (voltage increase or decrease) and only adjusts the most recently performed action if the trend has changed during a certain time frame. The time delay depends on the voltage deviation from the trend.

Protection against overheating (due to prolonged overload e.g.) The Cyrix disconnects in case of excessive contact temperature and recovers after cooling down.
