• A 1:1 connection is used. The maximum cable length is 15 m. To extend
the transmission path, use the OMRON Z3R RS-232C Optical Interface.
• Use AWG24 (cross-sectional area: 0.205 mm
tional area: 2.081 mm
• Connect terminals 11 and 12 when using the E5CN-@@PH as the exter-
nal power supply for the ES1B.
• Connect terminals 14 and 15 when using the E5CN-@@PB as the exter-
nal power supply for the ES1B.
• Connect terminals 14 and 15 when using the E5AN/EN-@@P as the
external power supply for the ES1B.
