Tinycontrol SSR-40DA

Modern solid-state relay FOTEK SSR-40DA for contactless switching of high currents

This new generation solid-state switch (Solid State Relay) is designed for industrial applications requiring reliable switching of alternating voltages at high currents. Thanks to the absence of mechanical components, it offers many times higher service life compared to traditional contactors and allows trouble-free operation even at high switching frequency.

The relay is equipped with photoelectric isolation between input and output and an LED indicating the operating status. With an operating voltage of 24 to 380 V AC and a maximum switching current of 40 A, it represents a universal solution for a wide range of industrial applications.

• Contactless switching of alternating voltages with high currents up to 40 A.
• Many times higher service life compared to traditional contactors due to the absence of mechanical components.
• Trouble-free operation even at high switching frequency and fast response under 10 ms.
• Wide operating voltage range of 24 to 380 V AC for universal use.
• Control voltage of 3 to 32 V DC with a current of 4.5 to 20 mA for easy integration.
• Photoelectric isolation between input and output for maximum safety.
• LED signaling diode informing about the operating status of the relay.
• Wide operating temperature range from -30 to +80 °C.

Industrial applications

The SSR-40DA relay is ideal for automation systems, heating control, motor switching, lighting and other devices requiring reliable switching of high currents without mechanical wear.

Advantages of semiconductor relays

Unlike electromechanical relays, they do not contain moving parts, which eliminates mechanical wear and sparking of contacts. The result is quiet operation, higher reliability and longer service life of the entire system.

Mounting and installation

The relay is equipped with mounting holes with a pitch of 48 mm for easy installation. During assembly, it is advisable to use thermally conductive paste and possibly a heat sink for heat dissipation when switching high currents.
