As automotive systems move toward faster charging and higher voltages, thermal risks increase—particularly in compact battery packs or high-load components. The HISO-T-8-2L addresses this with both mechanical simplicity and electrical robustness, making it suitable for use in multi-channel test environments where modularity, safety, and signal clarity are key.

n

The module slots directly into the CANSASflex ecosystem and is fully compatible with CANopen protocols, enabling real-time communication with control systems or data loggers in test labs and development rigs.
