Complete Tigo RSS Transmitter Kit for Rapid Shutdown
The Tigo RSS Transmitter Kit packages the DIN rail RSS Transmitter with an AC power source, so you are not hunting for a separate 12VDC supply. The 492 kits use a 120/240VAC power source and include Tigo's outdoor enclosure. The 493 kit is a dual core transmitter with a 480/277VAC power source for commercial three-phase sites.
Each transmitter sends the PLC keep-alive signal that Tigo TS4-A-F and TS4-A-2F devices need to stay energized.
Why You'll Love The Tigo RSS Transmitter Kit
Everything in one box. Transmitter, core(s) and power source together, ready to mount.
Weather protection. The 492 kits include the Tigo outdoor enclosure, rated IP67 and NEMA 3R.
Pure Signal technology. Syncs one coordinated keep-alive signal across multiple transmitters to mitigate crosstalk.
Code compliant. Tigo lists NEC 690.12 2017, 2020 and 2023 compliance with automatic or manual shutdown.
Your life, with the Tigo RSS Transmitter Kit
Your installer mounts one tidy box near the inverter, clips the core around the string conductors and wires it to AC. Inspection goes smoothly, and the array shuts itself down safely whenever the AC is off.
