Power Supply Connection
】
This series provide 4-pin 7.62mm pitch
input
terminal
blocks,
and
two
independent DC power supply systems of
P1 and P2. It could be used individually or
connecting to two independent DC power supply systems
externally. The power supply supports non-polarity and
anti-reverse connection, which could still work after reverse
connection.
Input voltage of power supply: 12VDC
～
48VDC
【
Relay Connection
】
This series provide 2-pin 7.62mm pitch input
terminal blocks. Relay terminal blocks are a
