Functional Features: Optocoupler isolation between input and output. Silent operation with no moving parts. Zero-crossing circuitry minimizes inrush currents and electromagnetic interference (EMI).

Application Scenarios: PLC output interfaces, temperature control systems (ovens/heaters), motor starters, and lighting controls.

Material Composition: Thermally conductive epoxy encapsulation with a ceramic substrate for insulation and heat dissipation.

Installation Requirements: Must be mounted on a heatsink to manage thermal load. Use thermal paste between the relay base and the heatsink.

Precautions: Do not exceed the maximum surge current rating. Ensure adequate ventilation around the heatsink. Verify the snubber circuit is present if switching highly inductive loads to protect the TRIAC.
