The MCOM300IO provides 8 channels for digital
input, 8 channels for digital output and 8 channels for
Analog input,analog
outputs are 12 bit at ±10 V/ ±5 V/ 0 ~ 10 V/ 0 ~ 5 V /4 ~ 20mA, each of which features
photocouple isolation. The MCOM300IO supports
source-type output, input is sink-type. Support RS485
Modbus RTUprotocol for communication and work as
slave device. Provide DIP switch for modbus
device id
and
Baud rate selection.
