Tigo 490-00000-52 RSS Transmitter Pure Signal Dual Core

Tigo 490-00000-52 RSS Transmitter Pure Signal Dual Core 120/240VAC. Power supply and enclosure not included.

The Tigo RSS (Rapid Shutdown System) Transmitter completes the cost-effective rapid shutdown system architecture when paired with Tigo's UL-certified Fire Safety solutions - including the TS4-A-F (add-on), TS4-A-2F (add-on for two modules). The RSS Transmitter sends a signal via PLC (Power Line Communication) to the TS4-F units to keep PV modules connected while powered on. TS4-F units automatically enter rapid shutdown mode when the RSS Transmitter is switched off and resume energy production when power is restored to the RSS Transmitter. The RSS Transmitter with Pure Signal technology can link multiple RSS Transmitters together, enabling one coordinated keep-alive signal to the array to maximize signal integrity, even in large and complex solar installations. This solution complies with NEC 2014, 2017, and 2020 690.12 rapid shutdown specifications utilizing power-line communication (PLC). Available with Pure Signal technology for multi-transmitter sites, as a Kit, DIN Rail, or PCBA for integration into inverters.

FAQs

• Can I use an RSS transmitter with the TS4-A-F?
  Yes, in fact an RSS transmitter is required for the TS4-A-F or the TS4-A-2F to function.
• Can I use a dual core transmitter with a TS4-A-F?
  Yes, you would simply not use the second core. You can install the second core if the run is greater than 1000 feet or if you have more than 10 strings on that core.
• What can I use as a power supply for the Tigo RSS Transmitter?
  Per Tigo's AC Adapter / Power Supply Overview, you can use an AC adapter or a DIN mount power supply like the DR-15 Series Power Supply as long as either option you choose meets required specifications.
• Can two RSS transmitters be powered from the same power supply?
  Yes, but you must measure that each unit is receiving 12V and you cannot double lug. Power must be distributed evenly. Crosstalk would be a major concern, so required design practices would be essential (refer to the RSS Installation Guide). If equipment will be in close proximity, you should use Pure Signal to mitigate crosstalk.
• Are the Tigo RSS Transmitter cores current transformers (CTs)?
  No, the Tigo RSS Transmitter cores are not CTs. The cores facilitate the signal to be transmitted on the DC wiring. Please refer to Tigo Communication Basics. If you need a CT, you may want to consider purchasing a meter.
