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.

Terminal function description
Analog ground, internally isolated from COM
Analog input 4
Input 0~10V: input impedance 22KΩ
+24V, PT, PLC and digital input and output
public terminal
Provides +24V power supply to the outside,
generally used as digital input and output terminal
working power supply and external sensor power
supply
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.
