Wiring System and Field Power
Wire range: 12 to 26 AWG (Ferrule diameter: 2.0 to 0.4 mm)
Wire strip length: 10 mm
Unit: mm (in.)
CAUTION
Be sure to note the maximum possible current for each power wire and common wire. Observe all electrical
codes dictating the ma
ximum current allowable for each wire size. If currents exceed the maximum rating,
the wires will overheat, which could cause serious damage to your equipment. For safety reasons, we
recommend using 2
-mm diameter wire to connect to the power supply (e.g., 12 AWG).
NOTE
P
owering the unit requires connecting both the system and field power to the power supply. If only one of
the power
sources is connected, the device may not work properly.
NOTE
W
e recommended using different power supplies to ensure that the system power and field power are
isolated from each other
. If using the same power supply for system power and field power, 3 KV or above
isolation between them is recommended.
System Power
This device requires a 12 to 48 VDC system power input. The system power powers this device and the
expansion modules via an internal bus, which is galvanically connected to the system power supply.
The amount of system current required to support an expansion module is 1 A. If more modules and more
power consumption is needed, an additional power module (45MR-7210) is required. Below is an example:
•10 x 45MR-1600 (59.4 mA) = 594 mA
•5 x 45MR-3810 (187 mA) = 935 mA

ioThinx 4530 Series Hardware Manual Hardware Installation
3-3
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
W
hen booting up the device in a low temperature environment, it may take up to two minutes until the
device
is up and running.
NOTE
To avoid damaging your devices, r
eset all power supplies connected to this device and 45MR-7210 modules
at the same time
.
Field Power
This device provides 12/24 VDC field power input, which is a passive power supply without protection and
the maximum current output is 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:
Pin Media Direct Interface Signal
1 Tx+ (transmit)
2 Tx- (transmit)
3 Rx+ (receive)
4 Not used
5 Not used
6 Rx- (receive)
7 Not used
8 Not used

4 CTS RXD- DATA2-
5 GND GND GND
NOTE
Connect the signal common pin (
e.g. GND pin on the serial port pin assignment) between each of the serial
device units. For insulated wire (shielding cable)
that is used to reduce electrical noise, connect the cable
shield drain wire to the chassis ground.
NOTE
To ensure that wires are
securely connected to terminal block connectors, strip 7 to 9 mm of insulation off
the ends of the wires before connecting them to the terminal block
.
Serial Console (Debug Port)
The serial console gives users a convenient way of connecting to the programmable controllers. This method
is particularly useful when using the computer for the first time. The serial console is also effective for
connecting to the Moxa programmable controllers when you do not know target network settings and IP
addresses.
