2.4.3 FX3GC Series main unit (24 V DC Input)
This section describes the input specifications of the FX3GC Series main unit. Note that the simultaneous
turning-on rate is restricted for the input extension units and the main unit. For details on this restriction, refer
to the following manual:
Refer to the FX
3GC Hardware Edition.
*1. If inputs X000 to X007 are assigned to the zero-phase signal of the DSZR instruction or the near-point
signal (DOG) of the ZRN instruction, the input response time will be as shown in the following table.
*2. PNP open collector transistors are supported only by the FX
3GC-32MT/DSS.
1. Internal input circuit
*3. A UL Listed or Recognized fuse rated not higher than 3.47 A must be used with FX3GC.
