Shortlist from the application
Input and switching mode
Match DC/AC control signal, zero-cross, random-on or phase-angle control to the process.
Load and current
Define resistive, inductive or capacitive load, nominal current, inrush and fault conditions.
Thermal design
Size the heatsink, airflow and derating from measured ambient and enclosure conditions.
Protection and installation
Review overvoltage, short-circuit, fuse, snubber, terminal spacing and mounting torque.
What to send for an accurate recommendation
Solid State Relays FAQ
How do I prevent SSR overheating?
Use appropriate current derating, a correctly sized heatsink, thermal interface material, ventilation and temperature verification under the real duty cycle.
Can XURUI customize an SSR?
Input signal, current and voltage class, control mode, housing or packaging requirements can be reviewed for OEM applications.
Are SSRs suitable for inductive loads?
Selected SSRs can control inductive loads, but current derating, surge behavior and protection must be designed specifically for the load.
Can SSRs connect to PLC outputs?
Many industrial SSRs are designed for PLC-compatible control signals. Confirm input voltage/current and off-state leakage for the exact model.
