Omron
The Omron G3PA-420B-VD-2-12-24VDC is a single-pole, ON/OFF control G3PA solid-state relay featuring DIN rail mounting and screw terminals. This unit operates within an AC voltage range of 200 to 480 V, supports an operational current of 180 to 528 V, and provides a rated load current for close mounting of 20 A with a permissible I²t value of 1800 A²s. It requires a DC supply voltage of 12 to 24 V, drawing a maximum control current of 7 mA, with a must-operate voltage maximum of 9.2 V, a must-release voltage minimum of 1 V, and dimensions of 100 mm in height, 37 mm in width, and 100 mm in depth at a maximum operating temperature.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Omron references — within one business day.
For a faster response, include quantity, condition, and delivery destination.
