External Power Input

External power input: +6.0 VDC to 12.5 VDC (9 VDC power supply included)

External power supply (included; required for USB-SSR24)

MCC p/n CB-PWR-9: 9 V @ 1.67 A

External Power Output

External power output (current range): 4.0 A max

USB-SSR Series devices monitor the external +9 V power supply voltage with a

voltage supervisory circuit. If this power supply exceeds its specified limit, the

PWR LED turns off, indicating a power fault condition.

External power output (voltage drop between power input and daisy chain

power output: 0.5 V max

The daisy chain power output option allows multiple MCC USB boards to be

powered from a single external power source in a daisy chain fashion. The

voltage drop between the module power supply input and the daisy chain

output is 0.5 V max. Users must plan for this drop to assure the last module in

the chain receives at least 6.0 VDC. A user-supplied custom cable is required

to daisy chain multiple devices.

USB Specification
