Tigo RSS Transmitter PV Rapid Shutdown Transmitter

Product Overview

The Tigo RSS Transmitter is the PLC keep-alive transmitter for Tigo Fire Safety rapid-shutdown systems. Paired with TS4-A-F or TS4-A-2F module units, it holds modules in the “on” state while powered. When the transmitter is de-energized (emergency stop, AC loss at the transmitter supply, or intentional shutdown), TS4-F units enter rapid shutdown.

Many UL PVRSS-certified inverters include a built-in Tigo RSS transmitter; use this standalone transmitter when the inverter does not provide that keep-alive path or when the design calls for an external DIN-rail / enclosure-mounted transmitter.

Best For

• TS4-A-F / TS4-A-2F rapid-shutdown systems needing an external transmitter
• Inverters without an integrated certified RSS transmitter
• Completing a Tigo Fire Safety bill of materials

Key Features

• PLC rapid-shutdown transmitter for Tigo Fire Safety
• Keep-alive architecture with TS4-A-F and TS4-A-2F
• Works with UL PVRSS-certified system pairings

Key Specifications

• Product: Tigo RSS Transmitter
• Role: PLC keep-alive for TS4-F family
• Companions: TS4-A-F (1 module), TS4-A-2F (2 modules)
• Mounting: typically DIN-rail / enclosure per kit variant — confirm the exact SKU packaging on your order

Compatibility / Important Considerations

• Required companions: TS4-A-F and/or TS4-A-2F on every module (or module pair). Transmitter alone is incomplete.
• Do not place two transmitters on the same string keep-alive path. If the inverter already has an integrated RSS transmitter, follow Tigo/inverter pairing rules.
• Related outdoor single-core kit SKU 492-00000-51 packages transmitter + supply + enclosure — choose the form factor your install needs.
• Route PV conductors through the transmitter core as shown in the Tigo installation manual; observe string count and current limits.
