RSD-S-PLC Rapid Shutdown Device | APsmart
Ensure NEC-compliant solar safety with APsmart’s RSD-S-PLC module, engineered for fast, reliable shutdown during emergencies.
Designed for residential and commercial solar systems, the APsmart RSD-S-PLC provides seamless integration with SunSpec-compliant inverters and PLC transmitters. When paired with an APsmart Transmitter-PLC, this device constantly monitors the heartbeat signal to maintain system operation. The moment this signal is absent—either automatically or manually via breaker switch—the RSD-S-PLC triggers a rapid shutdown, immediately cutting power at the module level. Its rugged, IP68-rated design and wide voltage range make it a dependable choice for both off-grid and grid-tied applications.
