256 max I/O per rack (up to 8 expansion modules each)
Add up to 31 MBIO racks using Modbus RTU
Add up to 247 MBIO racks using Modbus TCP
Use this tool multiple times to configure additional racks
Max remote I/O count: 63,232 points (using Modbus TCP)
Starting price:$300.00

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

Notes:

When using Remote I/O protocols the remote I/O is updated every scan (synchronous with local I/O). Modbus protocols update remote I/O using RD/WR instructions (asynchronous to the scan).
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.
