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.

Power supply
PW
External power
Used to provide input digital working power from
the external to the internal.
Voltage range: 12–24V
PW and +24V have been short connected before
delivery.
AI and AO
