Performed functions
- galvanic decoupler to control (test) of power circuits from a power line;
- protection of output power circuits against a short circuit with automatic traffic lights shutdown;
- monitoring of lamps blowing (breakage);
- detection of “red” and “green” lights conflict with automatic traffic lights shutdown;
- monitoring of power circuits locking between each other.
Features & Benefits
