4.3.4.3 Wiring for Source Type Output (FCU7-DX621/DX711/DX721/DX731)
(Note 1) Connect +24V to either or both of the flat connector 1B, 2B (24VDC). (*1)
(Note 2) Connect +24V (GND) to the flat connector 3A, 3B, 4A, 4B (24VDC). (*1)
Decide the number of 24VDCs to wire with regard to the total amount of each connector's maximum output
current and the voltage drop by the cables. The rated current is 1A per connector pin.
(Note 3) Connect 0V (GND) to the flat connector 1A, 2A (GND). (*2)
(Note 4) When large current flows due to small amount of connected load, fuse may be blown out or 24V power supply
voltage may drop. In order to secure the appropriate current value, watch the connected load.
