DC Supply
The RTCU AX9i eco unit can be supplied with 8-36VDC from an external DC power source.
Positive power is applied to the DCIN pin and ground is connected to the XGND pin.
The DC supply of the RTCU AX9i eco is protected against wrong polarity. If a system ground are
connected to either SGND or AGND a wrong polarity on the supply lines will destroy the internal
GND connection.
Please Note:
Minimum 16VDC supply is necessary for digital inputs 1-4 to work as S0 compliant inputs.
