External power input
External power supply (included)

MCC p/n CB-PWR-9V3A

6.0 VDC to 12.5 VDC (9 VDCpower supply provided)
9 V ±10% @ 3 A

Operating current

All relays off, Ethernet idle

250 mA typical, 320 mA max.

All relays on, Ethernet idle

1.3 A typical, 1.6 A max.

All relays on, Ethernet active

1.45 A typical, 1.7 A max.

Note 1:The E-PDISO16 monitors the external power supply with a voltage supervisory circuit. If thispower supply exceeds the supervisor limits, the POWER LED will turn off, indicating a power
fault condition.

4.0 A max.
0.5 V max.

Compatible cable(s) for daisy chain
Note 2:x = 2, 3, or 6 feet

The daisy chain power output option allows multiple Measurement Computing boards to be
powered from a single external power source in a daisy chain fashion. The voltage drop between
the module’s power supply and the daisy chain output is 0.5 V max. Users must plan for this drop
to ensure the last module in the chain will receive at least 6.0 V.
