(Total transmission length: 50 m max.)
Note The CJ1W-CIF11 is not insulated, so the total transmission distance for the whole transmission path is
50 m max. If the total transmission distance is greater than 50 m, use the insulated NT-AL001, and do
not use the CJ1W-CIF11. If only the NT-AL001 is used, the total transmission distance for the whole
transmission path is 500 m max. Refer to the wiring examples in Appendix G CJ1W-CIF11 RS-422A
Converter for wiring diagrams and settings when combining the CJ1W-CIF11 with the NT-AL001. When
the CJ1W-CIF11 is combined with the NT-AL001, however, the total transmission length is 50 m max.
