Omron G3PW-A220EC-S-FLK Solid-state Relay
Omron G3PW-A220EC-S-FLK is a single-phase G3PW power controller with a 20 A rated operational current and constant-current control. Its rated operational voltage is 100 to 240 V, while the operating range extends from 85 to 264 V. The model accepts a 1 to 5 V control input and uses screw terminals. Heater burnout detection and Serial RS-485 communication are included in the supplied specification, together with a permissible I²t value of 400 A²s and a 5 kW heater capacity. The operating temperature range is -15°C to 55°C. The G3PW-A220EC-S-FLK series unit is listed under the SSR and power controller lineup from Omron power-control components.

The Omron G3PW-A220EC-S-FLK Solid State Relay is a single-phase power controller rated at 20 A and specified with constant-current control. It has a 100 to 240 V rated operational voltage and an 85 to 264 V operating range, with a 1 to 5 V control input. Unlike the C-FLK row, this version is listed with screw terminals. Heater burnout detection and Serial RS-485 communication are included in the supplied specification. The permissible I²t value is 400 A²s and the heater load capacity is 5 kW. Operating temperature is specified from -15°C to 55°C. These structured values establish its control, current, voltage, terminal, communication, and thermal limits.
The S-FLK entry retains the same 20 A rated current, 100 to 240 V voltage class, 85 to 264 V operating span, and 1 to 5 V control signal as its closely related C-FLK counterpart. Its row also confirms constant-current control, heater burnout detection, and Serial RS-485, so those attributes can be used to distinguish it from the standard-control EU variants in the same G3PW family. A 400 A²s permissible I²t value and 5 kW heater-capacity figure are also listed. For the related model that adds a push-in and screw terminal arrangement while keeping the same current and communication features, see G3PW-A220EC-C-FLK.
