BOSCH FLM-7024-ISO Loop isolator module

The FLM-7024-ISO MUX bus isolator module is placed between devices on the MUX bus. A short circuit on the bus causes the isolators adjacent to either side of the short to activate. This effectively separates all devices between the activated isolators from the rest of the bus. This prevents failure of the entire bus. Once the short circuit is resolved, the isolators automatically restore normal operation of the entire circuit.

Basic Functions
