Haltech IO 12 Expander Box A CAN Based 12 Channel (Box Only)

This is the Haltech IO 12 Expander Box, a CAN-based unit that gives you 12 extra channels for inputs and outputs. If you're running a Haltech ECU and need to monitor more sensors or control more accessories than your ECU natively supports, this box is a straightforward way to add that capability. It communicates over the CAN bus, so it integrates cleanly with your existing Haltech setup.

The box itself is well-built, designed to handle the vibrations and conditions found in a performance vehicle. It's a component that expands the data logging and control options for your engine management system. You'll be able to add things like extra temperature sensors, pressure sensors, or even trigger additional relays or fans, all managed through your Haltech ECU.

Keep in mind this unit is not CARB approved and cannot be shipped to California. Ensure your Haltech ECU is compatible with CAN expansion modules before purchasing.
