DC Supply
The RTCU NX-910 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 NX-910 is protected against wrong polarity. If a system ground is connected
to either SGND or AGND, a wrong polarity on the supply lines will destroy the internal GND
connection.
Please Note:
➢
Minimum 15VDC supply is necessary for 0-10V analog output and 12V DC out.
➢
Minimum 16VDC supply is necessary for digital inputs 1-4 to work as S0 compliant inputs.
