Depending on the product, available terminal options are typically solder pin terminal (for PCB), solder hook (for wire harness), socket pin mount (for relay socket mount), and threaded terminal (lug/bus bar mount).
SSRs have a variety of other names depending on the maker or supplier. For example, Omron calls them MOS FET relays, while Toshiba calls them photo relays (Table 1). Table 1: Although the core operating principle is the same, different suppliers use a variety of designations for their SSRs, some highlighting their … See more The standard SSR has a single normally open (NO) output arrangement. However, there are many applications which need the opposite, a normally closed (NC) configuration, with the output stage opening when power … See more Although SSRs are fairly rugged, there are situations where they need some additional protection.
