Goodrive270 series VFD for fan and pump
Indicator
LED4
EC-IO501-00 can be used in scenarios where the I/O interfaces of VFD cannot meet the application
requirements. It can provide 4 digital inputs, 1 digital output, 1 analog input, 1 analog output, and two
relay outputs. It is user-friendly, providing relay outputs through European-type screw terminals and
other inputs and outputs through spring terminals.
