Multi-Modular I/O System
Power Supply Requirements
DC Power supplies used with the F6 and connected to the Euroblock terminal connector or the 4-pin XLR jack
must meet the following requirements:
Power Supply Rating Requires a UL60950-1 Certified/Listed ITE power
supply having a SELV (Safety Extra Low Voltage) rated
output voltage between 30 and 60V DC
Voltage
(measured at the input of the
F6 Modular I/O Frame)
30-60VDC, inclusive of tolerance
Maximum Current
(varies with input voltage)
(voltage at the input of the F6
Modular I/O Frame)
1.08A @ 60V
1.16A @ 56V
1.35A @ 48V
1.41A @ 44V
2.70A @ 24V
2.95A @ 22V

: When powering the F6 Modular I/O Frame through the Euroblock or 4-pin XLR input with a switching
power supply, an in-line EMI filter may be needed to meet the conducted emissions requirements of
EN 55103-1 and FCC Class B. This filter is not required when the unit is powered by a linear supply.
Power Cable Lengths
Maximum usable distances for DC power cables used with the F6 and connected to the 4-pin XLR or Euroblock
terminal block connectors will vary based on the gauge of the wire, and the voltage and power rating of the
supply. The cable will dissipate some of the power as heat resulting in a voltage drop on the cable that increases
with cable length.
The following table presents power cable length as a function of wire gauge and supply voltage/power rating.
