USB DIO High Voltage and Relay

External Power Input

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

External power supply (included)

USB-ERB08

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

USB-ERB24

MCC p/n CB-PWR-9V3A: 9 V ±10% @ 3 A

External Power Output

External power output (current range): 4.0 A max

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

power output: 0.5 V max

USB-ERB Series devices monitor the external +9 V power supply volt-

age with a voltage supervisory circuit. If this power supply exceeds its

specified limit, the

PWR LED turns off, indicating a power fault condition.

A user-supplied custom cable is required to daisy chain multiple devices.
