7.3 Connection of Remote I/O Power
+24VDC is required to run the remote I/O unit. Prepare a stabilized power supply that satisfies the
following conditions.
Output voltage +24V ±5%
Ripple ±5% (P-P)
FCUA-DX10* 2.4A or more
FCUA-DX11* 3.8A or more
FCUA-DX12* 3.8A or more

FCUA-DX14* 3.4A or more
The +24VDC power for the control circuit is supplied from the connector DCIN on the bottom of the unit
or from connectors DI-L, DI-R, DO-L or DO-R on the front. When supplying from the front connector,
supply to all corresponding pins.
When manufacturing the R300 cable, use the single-end connector CN300 (optional, with one end),
and when manufacturing the R301 cable, use the connector set CS301 (optional, with two ends).
