No-contact relays that semiconductor is utilized, which enables high-speed and high-frequency operation. OMRON provides Solid-state Relay for enormous range of applications.
SSR Internal Circuit Configuration Examples
|AC load||Yes *1||Photo-|
G3NA (AC input)
G3PE (single phase)
G3NA (DC input)
|Yes *1||Phototriac||G3PE-2(N) (three|
|Yes *1||Phototriac||G3PE-3(N) (three|
1.The zero cross function turns ON the SSR when the AC load voltage is 0 V or close to 0 V. SSRs with the zero cross function are effective in the following ways.
・ Clicking noise when a load is turned ON is reduced.
・ Effects on the power supply are reduced by suppressing inrush current with loads, such as lamps, heaters, and motors, thereby reducing inrush current protection circuits.
2. For 200-V models, use a triac on the output switching elements.
