Haltech IO 12 Expander Box B CAN Based 12 Channel w/Flying Lead Harness

The Haltech IO 12 Expander Box B is a CAN-based expansion module that adds 12 channels of input/output capability to your Haltech ECU system. This unit is designed for tuners and racers who need to monitor and control more parameters on their vehicle. It connects to your Haltech ECU via the CAN bus, allowing for seamless integration and data sharing. This expander box is particularly useful when you're running out of available inputs and outputs on your main ECU, or when you need to add specialized sensors and actuators.

This expander box is well-built with a durable enclosure to protect the electronics. It comes with a flying lead harness, giving you flexibility in how you connect your sensors and devices. The 12 channels can be configured as either inputs or outputs, offering significant versatility for custom setups. Whether you need to add more temperature sensors, pressure sensors, or control additional accessories like cooling fans or fuel pumps, the IO 12 Expander Box B can handle it. Its CAN-based communication ensures reliable data transfer with minimal latency, which is crucial for accurate tuning and real-time monitoring.

When integrating this expander box, ensure your Haltech ECU is running compatible firmware. The flying lead harness requires careful termination to ensure secure connections for all 12 channels. This unit is not CARB approved and cannot be shipped to California. Always refer to the Haltech installation manual for detailed wiring and configuration instructions to get the most out of your expanded I/O capabilities.
