Tigo 490-00000-52 300A Dual Core Pure Signal RSS Transmitter (No PS or Enclosure)

Dual-Core Pure Signal RSS Transmitter (DIN-Rail Mount, No Power Supply / Enclosure)

The Tigo 490-00000-52 is a DIN-rail mounted Rapid Shutdown System (RSS) transmitter featuring Pure Signal technology and a dual-core configuration. Designed for integration into commercial and utility-scale solar PV installations, this board-level component transmits a continuous Power-Line Communication (PLC) keep-alive signal over DC string homeruns to compatible Tigo rapid-shutdown receivers (such as the TS4-A-F and TS4-A-2F series).

Equipped with Tigo's Pure Signal technology, the transmitter allows multiple RSS units to synchronize across large multi-inverter commercial rooftops and ground mounts, eliminating crosstalk interference and PLC signal degradation. This dual-core version passes up to two independent DC conductor bundles through its dual current cores without requiring an external weatherproof enclosure or dedicated internal power supply.
