Description  The APsystems 406000 APsmart Transmitter-PLC is a dual-core rapid shutdown signaling device designed for photovoltaic (PV) systems. It works in conjunction with RSD-S-PLC units to ensure NEC 2017 (690.12) compliance by enabling module-level shutdown when required. This version does not include a power supply and supports SunSpec-certified signaling.     Technical Specifications  Condition New/Never Used Surplus Brand APsystems Category HVAC Part Number 406000  Subcategory HVAC Control System Board Signal Type Power Line Communication (PLC) Shutdown Type Rapid PV module shutdown (paired with RSD-S-PLC) Core Type Dual-core (29 mm ID) Power Supply Not included (external 85–264VAC or 180–550VAC optional) SunSpec Certification Yes NEC Compliance NEC 2017 (690.12) Operation Mode Signal present = normal operation, no signal = shutdown Form Factor Plug-in PCBA module Compatibility RSD-S-PLC modules Use Case Residential and commercial PV systems Protection Behavior Disables signal during AC power loss Communication Standard SunSpec Rapid Shutdown Signal Weight Not specified       Information About 406000 The 406000 is part of APsystems’ Rapid Shutdown System (RSS), delivering power line communication (PLC) signals to compatible RSD-S-PLC shutdown units. Engineered for grid-tied PV installations, the Transmitter-PLC helps maintain normal operation during grid presence and triggers rapid shutdown when de-energized. It features a dual-core design for robust signal transmission and offers compatibility with both residential and commercial power systems via optional external power supplies. The unit is SunSpec-certified and ensures streamlined compliance with 2017 NEC 690.12 requirements. Key Features: Dual Core Design: Enhances signal strength and stability for extended system reliability. SunSpec Certified: Supports standardized communication protocols for rapid PV module shutdown. NEC 690.12 Compliant: Meets 2017 National Electrical Code specifications for safety. No Power Supply Included: Can be paired with optional 85–264VAC (residential) or 180–550VAC (commercial) supply. Failsafe Operation: Signal stops automatically upon AC power loss, triggering shutdown. Heartbeat Signal Functionality: Maintains PV module activity while active; shuts down when signal is lost. Compact Construction: Supplied as a plug-in PCBA with 29 mm ID ferrite core rings. System Integration: Designed for use with APsmart RSD-S-PLC units in PV installations. The 406000 delivers the reliability and compliance required for safe, code-adherent PV system operation.
