Specifications

Power consumption

Table 3. Power consumption specifications

External power input

6.0 VDC to 12.5 VDC (9 VDC
power supply provided)

External power supply (included)

MCC p/n CB-PWR-9V3A

9 V ±10% @ 3 A

All relays off, Ethernet idle

250 mA typical, 320 mA max.

All relays on, Ethernet idle 1.3

A

typical, 1.6 A max.

Operating current

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 this
power supply exceeds the supervisor limits, the POWER LED will turn off, indicating a power
fault condition.

External power output

Table 4. External power output specifications

Parameter Conditions Specification
External power output - current range

See Note 2

4.0 A max.

External power output - voltage range

The input voltage minus the output
voltage at the daisy chain output.

0.5 V max.

Compatible cable(s) for daisy chain

C-MAPWR-x

x = 2, 3, or 6 feet

Note 2:

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.
