5.3 Performance specifications
*1 When connected to the FX1N Series PLC, up to two FX2N-64CL-M units can be
connected to the main unit and another two on the extension unit.
*2 FX2N-64CL-M draws 190mA from the 5V DC source.
The total 5V consumption of all special function blocks connected to the main
unit or extension unit must not exceed the 5V source capacity of the system.
(Refer to the Hardware manual of the PLC)
*3 Up to 7 units can be connected to an FX3UC-32MT-LT PLC.
*4 For the VCTF cable specifications, refer to the FX2N-64CL-
