ABB 07KR51 220VDC Advant Controller 31 PLC with CS31 Bus Expansion is the mains-powered control unit for AC31 applications: it runs the user program, reads eight 24 V DC inputs from sensors and switches six relay outputs for loads up to 2 A, all while talking to remote I/O over the CS31 bus. Because it accepts 230 V AC directly, it eliminates a separate 24 V power supply in cabinets where mains is the only available feed.
