external power supply.
Recommended cable specification: A02B–0124–K830 (5 m)
(On the external power supply side, an M3 crimp terminal is provided.)
Part of the 24 VDC power input to CP1A can be taken out from CP1B by
branching. CP1B should be connected as shown below. In this case, the
rating of the external 24 VDC power supplied to CP1A must be the sum
of the power consumed within the control unit and that supplied to
external equipment via CP1B. Up to 1.4 A can be supplied to the external
equipment.
