The EC-IO501-00 extension card can be used in scenarios where the I/O interfaces of a TD350 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.

Definition
On: The extension card is establishing a connection with
the control board.
Blinks periodically: The extension card is properly
State indicator connected to the control board (the period is 1s, on for
0.5s, and off for the other 0.5s).
Off: The extension card is disconnected from the control
board.
Power indicator On: The control board feeds power to the extension card.

Function
Function description
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
1. Output range: 0–10 V, 0–20 mA
2. Whether it is voltage or current output is
determined by J5.
3. Deviation ±0.5%; input of 5 V or 10 mA or
higher at the temperature of 25° C
