Retrofit 3-channel Relay module (5A per channel). Compact design for easy installation.

The 3 Relay TC Module (G4s) is a smart temperature control and relay switching module engineered for industrial automation, HVAC systems, and building management applications. Equipped with three independent high-reliability relays, this module enables accurate temperature-based control of electrical loads such as heaters, fans, compressors, pumps, and exhaust systems.

Built on G4s (Generation 4 smart) hardware, the module supports temperature sensor integration, manual logic configuration, and S-BUS communication, making it ideal for centralized and distributed automation networks. Each relay operates independently based on configured temperature thresholds, ensuring efficient energy usage and precise environmental control.

The rugged industrial design, combined with over-temperature and overload protection, guarantees long-term stability in demanding environments. Its DIN-rail mounting, USB firmware upgrade capability, and cascadable architecture make it a future-ready solution for scalable automation projects.

This module is perfectly suited for smart buildings, industrial panels, cold storage, process control, and HVAC automation, where dependable temperature-driven switching is critical.
