Tigo 492-00000-51 Single Core 100 Amp RSS DIN Rail Transmitter Kit

Product Description

The Tigo Single Core 100 Amp RSS DIN Rail Transmitter Kit is a module-level rapid shutdown (RSS) activation system designed for photovoltaic (PV) solar arrays that use Tigo TS4-A-F or TS4-A-2F rapid shutdown devices. It plays a critical role in meeting NEC 690.12 rapid shutdown code requirements for residential and commercial rooftop solar installations by enabling controlled shutdown of PV modules in emergency situations, such as fire response or maintenance.

When powered, the RSS Transmitter continuously sends a Power Line Communication (PLC) “keep-alive” signal over the PV DC lines to the connected TS4-F units, allowing them to remain active and supplying energy under normal operation. If grid power is lost or the transmitter is turned off, the TS4-F units automatically enter rapid shutdown mode, significantly reducing voltage on the DC side of the system to enhance safety for first responders and service personnel.

Key Features

Rapid Shutdown Compliance

• Meets NEC 690.12 rapid shutdown requirements for PV systems when used with Tigo TS4-A-F or TS4-A-2F units.

• Provides module-level voltage deactivation to improve fire and maintenance safety.

Reliable PLC Signaling

• Uses Power Line Communication to deliver consistent keep-alive signals to each TS4-F device, ensuring coordinated system operation.

• Optional Pure Signal™ technology enhances communication integrity, allowing multiple transmitters to work together in larger arrays.

Outdoor-Ready Construction
