2.4.2 FX3UC Series main unit (24V DC Input)
This section describes the input specifications of the FX3UC 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
3UC Hardware Edition.
*1. If inputs X000 to X007 are assigned to the zero-phase signal of the DSZR instruction or the interrupt
input of the DVIT instruction, the input response time will be as shown in the following table.
*2. PNP open collector transistors are supported only by the FX
3UC-MT/DSS.
*3. The FX
3UC-32MT-LT(-2) uses the display module for monitoring.
