Tigo RSS Transmitter Kit Single Core 492-00000-51 (DIN Rail, 120/240VAC Power Supply & Outdoor Enclosure)

The Tigo RSS Transmitter Kit Single Core (492-00000-51) is a complete rapid shutdown solution for outdoor solar installations, bundling the RSS Transmitter, a single RSS Core, DIN rail 120/240VAC power supply, and an IP68-rated outdoor enclosure in one pre-matched package. Together, these components form the rapid shutdown hub of a Tigo Flex MLPE solar system, enabling module-level deactivation of TS4-F units in compliance with NEC 690.12. Designed specifically for exposed installations where both weatherproof housing and clean DIN rail wiring are required, this kit lets installers deploy a commission-ready rapid shutdown node without sourcing and verifying compatible hardware separately.

What's included

• RSS Transmitter — DIN rail-mounted rapid shutdown transmitter; input 12VDC (±2%), 1A; sends continuous PLC signal to TS4-F units to keep modules energized while powered on
• Single RSS Core — handles up to 100A, 1500VDC max string voltage; supports up to 10 strings with up to 30 modules per string
• DIN Rail Power Supply — 120/240VAC input; mounts inside the enclosure and powers the RSS Transmitter directly
• IP68-rated Outdoor Enclosure — NEMA 4 weatherproof housing; combined dimensions 270 × 170 × 110 mm; suitable for direct weather exposure in any climate
• Not included: Tigo TS4-F modules (sold separately), conduit and weatherproof fittings for cable entry, mounting hardware

System specifications

• Rapid shutdown capacity: single RSS Core supports up to 100A, up to 10 strings, up to 30 modules per string, 1500VDC max
• Transmitter input: 12VDC (±2%), 1A
• Power supply input: 120/240VAC
• Shutdown signaling: PLC-based; automatic shutdown on power loss, automatic resume on power restore
• Environmental rating: IP68, NEMA 4 outdoor enclosure; operating temperature -20°C to 50°C (inside enclosure)
• Certifications: NEC 690.12 compliant for 2014, 2017, and 2020 code requirements

Eliminate component-matching guesswork

Sourcing an RSS Transmitter, RSS Core, DIN rail power supply, and outdoor enclosure separately means verifying compatibility across four line items before a single wire is run — and any mismatch surfaces only at the job site. This kit pre-engineers that decision: all four components arrive confirmed compatible, pre-selected for outdoor DIN rail deployment, and ready to commission immediately. Installers get automatic rapid shutdown functionality from the first power-on, cutting setup time on every installation.

Who this kit is built for

• Residential rooftop systems with Tigo TS4-F units — provides module-level rapid shutdown for homes using TS4-F (Fire Safety) units, with a single core covering up to 10 strings and 100A of array current.
• Smaller commercial arrays — the single RSS Core's 1500VDC and 100A capacity covers light commercial string configurations where a compact, self-contained shutdown node is preferred.
• Exposed or outdoor electrical installations — when the shutdown node cannot be housed indoors, the IP68, NEMA 4 enclosure is the correct specification for direct weather exposure in any climate.
• NEC 690.12 rapid shutdown compliance — the RSS Transmitter controls module-level deactivation for Tigo TS4-F systems to meet 2014, 2017, and 2020 code requirements on residential and commercial rooftops.
• New installations and retrofit upgrades — connects to any inverter via standard AC wiring, making it equally suitable for new builds and for adding code-compliant rapid shutdown to existing arrays equipped with TS4-F units.

How the components connect

The DIN rail power supply accepts 120/240VAC and steps down to the 12VDC the RSS Transmitter requires, with both units mounting inside the outdoor enclosure on a standard DIN rail. The RSS Transmitter sends a continuous PLC signal through the RSS Core to all connected TS4-F units, keeping PV modules energized during normal operation. When the transmitter loses power — either automatically on inverter shutdown or manually via a disconnect — the PLC signal ceases and all TS4-F units enter rapid shutdown mode within the NEC 690.12 timeframe. Power restoration automatically resumes the signal and brings modules back online. Buyers will also need conduit and weatherproof fittings for cable entry into the enclosure and Tigo TS4-F units installed on each PV module.

Why choose the Tigo RSS Transmitter Kit Single Core 492-00000-51?

The 492-00000-51 is the single-core variant in Tigo's RSS Transmitter Outdoor Kit lineup — the right configuration when one string group up to 100A needs code-compliant rapid shutdown in a weatherproof, rail-mounted package. Where sourcing components individually risks field incompatibilities, this kit removes improvisation from power delivery, core selection, and housing. For larger arrays requiring up to 200A across two string groups, the dual-core variant (492-00000-20) is available; the single-core kit is optimized for residential and smaller commercial systems where one RSS Core covers the full array.
