Applications

The 15 V DC LOGO!Power supply serves niche industrial applications — legacy automation equipment, specialty sensors and transmitters, and control circuits designed for 15 V operation. The -6SB10 suffix distinguishes 15 V variants from their 12 V counterparts (-6SB00) at the same current rating. For higher 15 V current requirements, the 6EP3322-6SB10 provides 4 A (60 W) in a 54 mm housing.
