Part Number: CP1W-CIF01
An RS-232C Option Board can be mounted to an Option Board slot on the CPU Unit. With a CPU Unit with 30, 40 or 60 I/O points, either Option Board slot may be used. When mounting an Option Board, first remove the slot cover. Grasp both of the cover's up/down lock levers at the same time to unlock the cover, and then pull the cover out. Then to mount the Option Board, check the alignment and firmly press it in until it snaps into place.
Caution:
Always turn OFF the power supply to the PLC before mounting or removing an Option Board.
