The GTD series consists of AC zero-crossing power solid-state relays with integrated heatsinks, built-in heater break diagnostics (HB function), selectable current scales, and adjustable setpoints.
Optional junction overheat protection is available for added safety. An alarm output is provided to signal fault conditions.
These relays are available in 25A and 40A ratings, with a maximum voltage of 480 Vac and Vdc logic input control.
Voltage transistors are safeguarded by MOV (varistor) protection, and all models are engineered to operate at rated currents with continuous conduction at 40°C. Refer to the dissipation curves for other operational conditions.
Thanks to their high-performance design, GTD relays support very short switching times and can perform millions of operations without component wear.
Optional accessories include front-panel mounting kits, fuses, and fuse holders for flexible installation.
