EC-IO502-00 can be used in scenarios where the I/O interfaces of a VFD cannot meet the
application requirements. It can provide four digital inputs, one PT100 temperature measuring
input (PT1+), one PT1000 temperature measuring input (PT2+), and two relay outputs. It is
user-friendly, providing relay outputs and digital inputs through European-type screw terminals
and temperature measuring inputs through spring terminals.
