Thông số kỹ thuật Allen bradley 1769-ECR:
With 1769-L3x and 1768-L4x controllers, if you divide 1769 modules into multiple banks, make sure:
- each bank needs its own power supply.
- use expansion cables to connect the banks.
- the last I/O bank requires an end cap.
How you orient I/O banks determines which expansion cables you need to connect the I/O banks.

The final I/O bank in 1769-L3x and 1768-L4x controller systems needs an end cap on the end without the expansion cable. The 1769-L23x controller comes with a right-end cap, so you do not need to order one separately.
