Frequency Inverter ST600 Series High-Performance Multifunction VFD Expansion cards
-316-
The SIO502-00 expansion card can be used in scenarios where the I/O interfaces of the VFD cannot
meet the application requirements. It can provide 4 digital inputs, 1 PT100 temperature measurement
input (PT1+), 1 PT1000 temperature measurement input (PT2+), and 2 relay outputs. It is user-friendly,
providing relay outputs and digital inputs through European-type screw terminals and temperature
measurement inputs through spring terminals.
