It carries an IP65 rating, so out here in the grease it'll handle washdowns and dust without blinking. The positive-opening contacts give you the mechanical guarantee for safety circuits, even though the module itself isn't an emergency-stop device. The 30 VDC rating matches the standard AS-i bus voltage; don't expect it to switch higher DC loads. The 54.5 mm depth and 45 mm width with a 200 mm height fit a standard 22 mm mounting hole — it'll drop into a panel cutout sized for a typical pushbutton station.","metaTitle":"Siemens 3SF5874-4EA AS-Interface Front Panel Module, 4I/4O S","metaDescription":"Siemens 3SF5874-4EA AS-Interface front panel module with 4 illuminated pushbuttons, 4 inputs/4 outputs, IP65, 30 VDC rated.
