ioThinx 4510 Series Hardware Installation
• 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.

Field Power
a field power input of 12/24 VDC that passes
directly through the expansion modules and provides a maximum
current output of 2 A.
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:
