The EC-IO501-00 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 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.

This indicator is on when the expansion card is
establishing a connection with the control board;
it blinks periodically after the expansion card is
properly connected to the control board (the
period is 1s, on for 0.5s, and off for the other 0.5s);
and it is off when the expansion card is
disconnected from the control board.
This indicator is on after the IO expansion card is
powered on by the control board.
The working power of digital input is
provided by an external power supply.
Voltage range: 12–24 V
The terminals PW and +24V are shorted
before delivery.
1. Input range: 0–10 V, 0–20 mA
2. Input impedance: 20 kΩ for voltage
input; 250 Ω for current input
3. Set it to be voltage or current input
through the corresponding function code.
4. Resolution: When 10 V corresponds to
50 Hz, the minimum resolution is 5 mV.
5. Deviation:±0.5%; input of 5 V or 10 mA or
higher at the temperature of 25°C
