USB DIO High Voltage and Relay

Specifications - USB-PDISO8 Series

External power output

External power output - current range: 4.0 A max

The daisy chain power output option allows multiple MCC USB products with

a USB hub output port to be powered from a single external-power source in a

daisy-chain fashion. The voltage drop between the device power supply input

and the daisy-chain output is 0.5 V maximum. Users must plan for this drop

to assure the last device in the chain receives at least 6.5 VDC. A user-supplied

custom cable is required to daisy chain multiple devices.

External power output: Voltage drop between power input and daisy chain

power output: 0.5 V max
