VFD500-IOEX1 Extension card
The VFD500-IOEX1 expansion card is a multi-function IO expansion card for VFD500 series inverters. It can expand 4
channels of DI, 2 channels of AI, and 4 channels of DO. Among them, AI4 can be used as ordinary voltage type input
analog quantity, and can also be used as PT100. Type or PT1000 type temperature detection input.
The terminal definitions of the VFD500-IOEX1 expansion card are shown in Table 7-10

Digital input power terminal
It is used for switching between high and low level
of switch input. It is short-circuited with +24V at the
factory, that is, DI is active at low level.
When the external power is input, disconnect the
PLC from the +24V.
It is a separate network from the PLC on the IO
board and is used separately.
