Product Details
The Victron Cyrix-ct 12/24 V 230 A Split Charge Relay (CYR010230010) is a robust and intelligent solution for managing dual battery systems in professional installations. Designed for trade customers in the vehicle, marine, and off-grid power sectors, this microprocessor-controlled relay automatically connects two battery banks in parallel when charging is detected, and isolates them once voltage drops.
Supporting both 12 V and 24 V systems through automatic voltage detection, it simplifies setup across a wide range of platforms. With a continuous current capacity of 230 A and a cranking burst rating of 500 A for five seconds, it delivers dependable performance in demanding environments.
Built for practicality, the Cyrix-ct features long M8 terminal bolts to accommodate multiple power cables, a clear LED status indicator, and a compact, durable housing. Its intelligent control logic analyses voltage trends to prevent unnecessary switching, ensuring longer relay life and consistent operation. An integrated Start Assist function also allows both batteries to be temporarily linked to support engine start-up in low-power situations.
Unlike traditional diode isolators, the Cyrix-ct eliminates voltage drop between batteries, maximising alternator efficiency and overall charge performance. With dimensions of 65 × 100 × 50 mm and a lightweight 0.27 kg body rated at IP54, it fits neatly into professional installations where reliability and space efficiency are key.
Ideal for installers working with motorhomes, boats, and off-grid systems, the Victron Cyrix-ct 12/24 V 230 A delivers a professional-grade, automatic battery management solution that ensures safe, efficient charging without power loss.

Key Features
- Intelligent Battery Monitoring: Prevents unwanted switching by analyzing the general voltage trend (increasing or decreasing). It reverses action only if the trend has reversed during a specific period, with time delays depending on the voltage deviation.
- No Voltage Loss: A high-efficiency alternative to diode isolators, maintaining full charge voltage to the batteries.
- Bidirectional Voltage Sensing: Senses the voltage of both connected batteries, allowing it to engage if either the starter battery or the accessory battery is being charged.
- Prioritising the Starter Battery: In a typical setup, the alternator is connected to the starter battery; the Cyrix engages to allow parallel charging of other batteries only after the starter battery has reached its connect voltage.
- Protection Against Overheating: Features built-in thermal protection that will disengage the relay in case of excessive contact temperature due to long-duration overload, re-engaging once cooled.
- LED Status Indication: Includes an integrated LED status indicator to show if the unit is engaged, disengaged, connecting, disconnecting, or in an alarm state (e.g., over-temperature or over-voltage).
Installation & Emergency Features
- Start Assist: Allows for a parallel connection in case of emergency. The Cyrix can be engaged manually with a push button or switch to connect batteries for 30 seconds, which is useful if the starter battery is discharged or damaged.
- Dual Power Supply: The unit will close even if the voltage on one battery is too low to operate the Cyrix, provided it is not lower than 2V (12V system) or 4V (24V system).
- Long Connection Bolts: Equipped with 16mm M8 bolts to allow for the connection of more than one power cable.
- Included Accessory: Comes standard with a 1-metre control cable.
