Know Different Products of Solid State Relay Board

A solid-state relay is an electronic switching tool that switches on or off when a small external voltage is applied across its control terminals. The main benefit of solid-state relays is unmatched long operation life, quick respond, silent operation and best fitting inductive loads.

A number of solid-state relay boards available on market are basically characterized by a number of parameters including the required activating input voltage, current, output voltage and current, whether it is AC or DC, voltage drop or resistance affecting output current, thermal resistance, and thermal and electrical parameters for the safe operating area.  At Online-Devices, we provide a wide range of high-quality solid-staterelay boards made by leading manufacturers around the globe at an affordable price.
