6.5 Expansion of Main Unit (Calculation of Current Consumption)
The amount of connectable extension equipment to the main unit varies, depending on the main unit type.
Please select equipment compatible with the main unit used.
There are three types of main units:
- AC power supply/DC input type: FX3U-M/ES(S)
- DC power supply type : FX3U-M/DS(S)
- AC power supply/AC input type: FX
3U-MR/UA1
1. When an AC power supply/DC input type main unit is used
• When only input/output extension devices are added, use the quick reference matrix.
Caution
Except for the FX2N-8ER and FX2N-8ER-ES/UL.
→ Refer to Subsection 6.5.1 "Quick reference matrix - when only input/output devices are added (AC
Power Supply/DC Input Type)".
• When special extension devices, FX2N-8ER or FX2N-8ER-ES/UL are added, calculate the current
consumption to ensure that the total current to be consumed by the added extension devices can be
supplied by the built-in power supply.
→ Refer to Subsection 6.5.2 "When special extension devices are also added [calculation of current
consumption] (AC Power Supply/DC Input Type)".
2. When a DC power supply type main unit is used
• When only input/output extension devices are added, use the quick reference matrix.
Caution
Except for the FX2N-8ER and FX2N-8ER-ES/UL.
→ Refer to Subsection 6.5.3 "Quick reference matrix [when only input/output devices are added] (DC
Power Type)".
• When special extension devices, FX2N-8ER or FX2N-8ER-ES/UL are added, calculate the current
consumption to ensure that the 5V DC and the internal 24V DC power can supply the total current required
by the added extension devices.
When the added extension devices include the FX0N-3A, FX2N-2AD, FX2N-2DA, FX3U-4HSX-ADP or
FX3U-2HSY-ADP, calculate the current consumption (internal 24V DC) at startup.
→ Refer to Subsection 6.5.4 "When special extension devices are also added [calculation of current
consumption] (DC Power Type)".
3. When an AC power supply/AC input type main unit is used
• When only input/output extension devices are added, use the quick reference matrix.
Caution
Except for the FX2N-8ER and FX2N-8ER-ES/UL.
→ Refer to Subsection 6.5.5 "Quick reference matrix [when only input/output devices are added] (AC
Power Supply/AC Input Type)".
• When special extension devices, FX2N-8ER or FX2N-8ER-ES/UL are added, calculate the current
consumption to ensure that the 5V DC and the internal 24V DC power can supply the total current required
by the added extension devices.
→ Refer to Subsection 6.5.6 "When special extension devices are also added [calculation of current
consumption] (AC Power Supply/AC Input Type)".
6.5.1 Quick reference matrix - when only input/output devices are added
(AC Power Supply/DC Input Type)
In the following quick reference matrix, the value at the intersection of the number of input points to be added
(horizontal axis) with the number of output points to be added (vertical axis) indicates the remaining power
supply capacity.
Caution
When the FX2N-8ER or FX2N-8ER-ES/UL are added, refer to Subsection 6.5.2.
