Use Modbus I/O Series racks to expand the I/O capabilities of ANY Modbus system!

Notes:

When using the Do-more Ethernet Remote I/O or Host Ethernet Remote I/O protocols the remote I/O will be seen as native to the CPU. Modbus I/O must use RD/WR instructions.
Power budgeting is required for all Remote I/O configurations. This selector tool will keep track of the power budget and alert you if your combination of I/O modules will exceed the power available from the Remote I/O controller.
