The GTS-L4 series integrates four miniaturized solid-state relays on a single aluminum heatsink, enabling independent control of four resistive loads.
Each channel is operated via a separate logic input with zero-crossing switching for precise power control.
Models are available for currents up to 15A and voltages up to 440Vac, ensuring reliable operation at rated conditions with continuous supply at 40°C ambient temperature.
Compact channel size and 4-way modularity make the GTS-L4 ideal for systems with multiple temperature-controlled zones.
These relays are fully compatible with Gefran’s GFXTERMO multichannel controllers for single-phase and bi-phase applications, and each channel can be replaced individually. Their high-performance design supports extremely short switching times and millions of operations without component wear.
Connections are made using Faston terminals, and the units can be mounted on DIN rails, panels, or a base.
