Indicator
Definition
Function
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.
LED4
Power
indicator
This indicator is on after the IO expansion card is
powered on by the control board.
The HD2-E-IO2 expansion card can be used in scenarios where the I/O interfaces of the inverter
cannot meet the application requirements. It can provide 4 digital inputs, 1 PT100 temperature
measurement input (PT1+), 1 PT1000 temperature measurement input (PT2+), and 2 relay outputs. It
is user-friendly, providing relay outputs and digital inputs through European-type screw terminals and
temperature measurement inputs through spring terminals.
