Note If the B7A Interface Unit is mounted to a Rack with a C200HW-PD024 24-VDC Power Supply Unit, supply
24 VDC from an independent power supply to the B7A Interface Unit or use a transformer to separate the
power supply line to the B7A Interface Unit from the power supply lines to the CPU Unit and I/O Power Sup-
ply Unit.
12 to 24 VDC
