The terminals are arranged as follows:
CME and COM are shorted through J3 before delivery, and J5 is the jumper for selecting the output type (voltage or current) of AO2.

Indicator definition
Indicator No. | Definition | Function |
LED1 | State indicator | This indicator is on when the extension card is establishing a connection with the control board; it blinks periodically after the extension 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 extension card is disconnected from the control board. |
LED4 | Power indicator | This indicator is on after the IO extension card is powered on by the control board. |
The EC-IO501-00 extension card can be used in scenarios where the I/O interfaces of a Goodrive350 IP54 high-ingress protection series 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.
