Field Power; Wiring Ethernet Ports - Moxa Technologies ioThinx 4510 Series User Manual

ioThinx 4510 Series
• 10 x 45MR-1600 (59.4 mA) = 594 mA
• 5 x 45MR-3810 (187 mA) = 935 mA
The total system current is 1.594 A, which is greater than 1 A. Therefore, an additional 45MR-7210 is
needed.
NOTE Install the 45MR-7210 to the left hand side of the module where the power consumption would be
exceeded.
NOTE To avoid damaging your devices, reset all power supplies connected to this device and 45MR-7210 modules
at the same time.

4500 series application:

Field Power

This device provides a field power input of 12/24 VDC that passes
directly through the expansion modules and provides a maximum
current output of 2 A.
NOTE The 12/24 VDC field power supply can be connected directly to 45MR modules. If more connection points
are needed, purchase 45MR-7820 (8 x FP+ and 8 x FP-) modules.

Wiring Ethernet Ports

The maximum cable length of a 10/100BaseT connection is usually stated as 100 m (350 feet), but the
actual limit for your application could be longer or shorter depending on the amount of electrical noise in the
environment. To minimize the amount of noise, Ethernet cables should not run parallel to power cables or
other types of cables that generate electrical noise. The following diagram and table shows the pin
assignments for the RJ45 Ethernet ports:
