ioLogik E4200 Initial Setup
2-6
ATTENTION
When the total current consumption for connected I/O modules exceed
s 1.5A, an M-7001 power expansion
module is required.
To determine if
an additional power expansion module is needed, open the
Power Consumption Spreadsheet
located here:
Program Files MOXA IO Server HELP. The spreadsheet requires Microsoft Excel to
operate. Once you enter the I/O modul
e quantity, the spreadsheet will compute automatically how many
power expansion modules are required.
When extra power expansion modules are installed, restart the system in the following sequence to ensure a
proper sta
rt-up.
Power Off Sequence
1.
Unplug the network adaptor’s removable terminal block.
2.
Unplug the expansion module’s removable terminal block.
Power Up Sequence
1.
Plug in the power expansion module’s removable terminal block.
2.
Plug in the network adaptor’s removable terminal block.
ATTENTION
The “End Module” should be covered to prevent unexpected damage to exposed data pins.
Installing the Field Power Module
The field power distributor is designed to isolate different field voltages. Most of the field power DIO/AIO
modules for the ioLogik E4200 series are 24 VDC. If you need to connect 110 VAC, 230 VAC digital input or
output modules, you must use the Field Power Distributor to isolate different field powers within a single ioLogik
E4200 system.
If all of the DIO modules are 110 VAC, you will need at least one field power distributor to isolate the field power
from the network adaptor (likewise when using 24 VDC or 230 VAC). For example, before you connect a 110
VDC or 220 VAC AC digital input module to a 24 VDC DI/O module, you will need an M-7002 field power
distributor.
Some types of Potential Distributor modules provide extra wiring points such as shielding ground, 0 V field
power, and 24 V field power. For example, the 8-channel digital input (sink type) module itself does not have
a 24 V wiring point, but you can add a 24 V potential distributor for easy wiring.
