ECI3808 Network Motion Control Card User Manual V1.5
Chapter IV Expansion Module
Control card can expand resources through CAN bus, including digital IO and analog
AD/DA resources. ZIO series expansion modules or ZMIO310-CAN coupler with sub
modules can be used. Please refer to corresponding expansion module manuals.
4.1.
CAN Bus Expansion Wiring
The ZIO expansion module is powered by the dual power supply. Except the main
power supply, an additional IO power supply is required to supply independent power for
IO. Both the main power supply and the IO power supply use 24V DC power supply. For
ZAIO, it only needs to connect to the main power supply.
To prevent interference, separate the IO power supply from the main power supply.
Please select the expansion module according to the requirements, and select IO
mapping or axis mapping according to the resources of the expansion module.
Wiring reference of connection between ZIO expansion module and control card and
standard wiring of CAN bus are shown as below (take ZMC408SCAN and ZIO1616 as the
example):
