Chapter III Expansion Modules
Please refer to
ZIO expand card hardware manuals
, also it can be expanded through
EtherCAT.
ZMC408SCAN controller uses single power. ZIO expansion module uses double power to
supply, in actual application, ZIO power channels on expansion modules can share the same
power supply. When ZMC408SCAN controller and ZIO module uses different powers, the
EGND of controller must be connected to the GND of expansion modules, otherwise CAN
bus may be burned out.
When multi expansion modules are linked on CAN bus, it is necessary to connect 120Ω
resistor between CANL and the CANH on the last IO expansion module.
