7.3 IO Extension card

 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 7-5.
