Victron GX-IO Extender 150 for GX Devices

The Victron GX-IO Extender 150 adds eight configurable digital I/O channels and a PWM output to a compatible GX device.

Eight channels can be used as eight inputs, eight outputs, or four of each. That flexibility is what makes it worth fitting rather than a fixed-function relay board, since a boat's requirements change as equipment is added.

Inputs read sensors and switches; outputs drive relays and controlled loads. So a bilge alarm, a tank sensor or a door switch can appear in the same monitoring system as the electrical data, and a pump or a light can be switched from it.

The PWM output supports variable control rather than simple on and off. That suits a fan, a dimmable light or anything else where a proportional signal is needed instead of a switch. Explore more power system monitoring and control.

• Eight in, eight out, or four of each
• Requirements change as equipment gets added
• Sensors and switches join the electrical monitoring
• PWM gives variable control, not just on and off
