System Architecture
The ioLogik E4200 modular I/O consists of a network adaptor that supports Ethernet and up to 16 I/O modules.
The ioLogik E4200 Active Ethernet network adaptor is the brains of the system. It is responsible for
collecting information from each I/O module and deciding what parameters to use to operate the I/O
module. Communication between the network adaptor and I/O modules is achieved by a system
communication bus.
Modbus addresses for each I/O channel are arranged dynamically by the network adaptor according to the
installed I/O modules.
The network adaptor requires two sets of 24 VDC power inputs. One is for the internal logic circuit, and the
other is for field I/O circuits.
The network adaptor provides 5 VDC power to all connected I/O modules. When the total current
consumption of the I/O modules exceeds 1.5 A, you will need to insert an extra power expansion module.
To determine how many power expansion modules are required, refer to the spreadsheet in Program Files
MOXA IO Server HELP.
