E-PDISO16 User's Guide 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.
