3. SIGNALS AND WIRING
3.2.2 Output signal
DO1A to DO3A, DO1B to DO3B, and DO4NA can be used as source output. DO4PB can be used as sink
output.
Note 1. Separate all the external wires by two types, CN10A and CN10B. Be sure to wire them separately by the two types for power
supply for IO (24 V DC, 0 V common). Do not mix them when wiring.
2. Assign each output device to the following combinations of connector and pin. For details of each device, refer to section 4.4.1
and 4.4.2.
3. Supply 24 V DC ± 10% to interfaces from outside. When all the I/O points are used, the required current capacity is 0.8 A in
total. The current capacity can be decreased by reducing the number of I/O points. Refer to section 3.3.1 that gives the current
value necessary for the interface. The illustration of the 24 V DC power supply is divided between input signal and output
signal for convenience. However, they can be configured by one.
4. DO4PA (CN10A-16), DO4NA (CN10A-18), DO4PB (CN10B-16), and DO4NB (CN10B-18) are not supported by MR-D30
manufactured in September, 2014 or earlier. Do not connect anything to the pins.
