Solid State Relay 6A 440V 660V 3-32VDC

• Optical isolation between input and output circuits.
• Control signal with TTL logic interface.
• Solid-state contactless switch output, no spark or arc during switching.
• Zero voltage turn-on and zero current turn-off at the output.
• PCB direct plug-in soldering structure, small size, easy installation.
• The product is mainly used for isolation control between weak and strong electrical currents in industrial automation. It can also be used as a driver stage for various high-power output devices and low-power appliances, such as motors, solenoids, and power supplies for contactless switch control.

• When selecting a product, different margins should be reserved in the current rating based on the nature of the load. For resistive loads, select 2-3 times the load current. For inductive or capacitive loads, select 3-4 times the load current.
• According to the relationship between load current and ambient temperature, if the ambient temperature is high or the heat dissipation conditions are poor, the current capacity should be increased. To prevent load short circuits during use, it is required to connect a fast circuit breaker or fast fuse corresponding to this product in series in the load circuit.
• For inductive loads, a varistor should be connected in parallel at the output end to prevent damage to the thyristor due to overvoltage. Varistor (MOV) selection: choose 430-470V for the 240V range, and 680V for the 440V range.
• This model is naturally cooled and does not require a heat sink during operation.
