The 6ES7222-1AD30-0XB0 is a SIMATIC S7-1200 Signal Board SB 1222 packing four solid-state digital outputs on a 5 V DC rail, switching at 200 kHz. Each output is rated 0.1 A resistive — enough for high-speed signaling to downstream logic or low-power actuators, not for driving contactors or solenoids directly. The MOSFET stage is current-sinking or current-sourcing, so it adapts to both NPN and PNP field wiring without a pull-up resistor swap. It draws 35 mA from the 5 V backplane bus and dissipates 0.5 W typical — negligible for the S7-1200 power budget, meaning it won't crowd out other signal boards on the same CPU. The 21 mm depth and 38 mm width keep it flush with the CPU profile, so it doesn't overhang the DIN rail or block adjacent modules. Temperature range spans -40 °C to 70 °C, with derated limits for vertical (50 °C max) and horizontal (60 °C max) installation. That covers most cabinet environments short of a foundry wall or freezer tunnel. The 95 % humidity ceiling at 25 °C (non-condensing) handles washdown-adjacent panels, though the board itself isn't IP-rated for direct spray.
Approvals and compliance
Carries cULus, UL, CSA, CE, FM, KC, marine, and RCM approvals — enough for machinery export to North America, Europe, Korea, Australia, and marine-class vessels. The lifecycle stage is current, so this is still an active catalog number with no announced end-of-life.
