The Flexball 4500 Twin is a surface-mounted version suitable for single and twin-engine vessels, made of seawater resistant stainless steel 316 and completely waterproof, IP67.
It can be connected to the Flexball control cabinet by means of the CAN bus signal, or directly to a motor controller (frequency controller) by means of a voltage (0-10V) or current (4-20mA) controlled signal.
In case of direct connection to a motor controller, this concerns the Flexball 4500 Twin ELT version.
