Product Details

GTK33 3A/6A SSR 3Phase din rail mount with heatsink

Opto-isolation between input and output loops.

Control signals are interfaced with TTL logic.

Light-emitting diodes (LEDs) indicate the operating status.

Built-in output solid state switch with overvoltage absorption protection at both ends.

Depending on the customer's needs, the output end can have additional auxiliary contacts.

Rail clamp, heat sink and switch components are integrated into one unit, small size and easy installation.

The products are mainly used for the isolation control of weak and strong power in industrial automation and also for small and medium power appliances. Contactless switch control such as electric motor, solenoid pilot actuated valve, solenoid, well heater, etc.
