Isolation Module A9057T
Features
- LPCB & CPR approval;
- In the event of a short circuit it isolates faulty parts of the loop;
- Automatically resetting once the fault has been cleared;
- LED lights indicate status.
Isolation Module A9057T; loop isolator (hereinafter referred to as A9057T), mainly used to isolate a portion of a short circuit on the bus, other devices on the bus to ensure normal operation. Upon elimination of the short circuit fault, A9057T can be isolated out their own part back into the system. It is worth noting: A9057T using the bus to facilitate the determination of the location of a short circuit.
